If the federal reserve decreases the reserve rate from 7% to 5%, how does this affect the amount of money that would result because of fractional-reserve banking from an initial deposit into a bank of $30,000?
Answers
30,000÷0.07=428,571
If the federal reserve rate is 5% the money supply would be
30,000÷0.05=600,000
The affect
600,000−428,571=171,429
Increase by 171429
Answer:
The total affect of the decrease in the interest rate = $29400
Step-by-step explanation:
The initial amount of money which has been deposited into the account = $30000
The rate at which the initial money was deposited = 7%
But it is given that the federal reserve decreases the reserve rate from 7% to 5%
Now, we need to find the affect of this decrease on the deposited money
The rate of change in the interest rate = 7 - 5 = 2%
So, The affect of this decrease = 2% of 30000
= $600
So, The money becomes = 30000 - 600
Therefore, The total affect of the decrease in the interest rate = $29400

A company manufactures and sells mini-recorders. A survey of office supply stores indicated that at a price of $82 each, the demand would be four hundred recorders, and at a price of $42 each, the demand would be nine hundred recorders. If a linear relationship between price and demand exists, which of the following equations models the price-demand relationship?
(Let x represent the price per mini-recorder and y represent the demand in hundreds.)
A. Y= -1/8x + 57/4
B. Y= -8x - 114
C. Y= -1/8x - 57/4
D. Y= -8x + 114
Answers
Final answer:
Using the two given points $(82, 4)$ and $(42, 9)$, the slope is calculated to be $-1/8$. Subsequently, by using the point-slope form of the line equation and simplifying, we find that the linear relationship between price and demand is described by $y = -1/8x + 57/4$, which corresponds to choice A.
Explanation:
To determine the linear equation that best models the price-demand relationship for the mini-recorders, we are given two points. At a price of $82, the demand is 400 recorders (4 hundred), and at a price of $42, the demand is 900 recorders (9 hundred). In the mathematical representation, these points are (82, 4) and (42, 9), where x is the price and y is the demand in hundreds.
To find the slope (m) of the line, we use the slope formula:
m = (y2 - y1) / (x2 - x1), which gives us m = (9 - 4) / (42 - 82) = 5 / (-40) = -1/8.
Now, we can use the point-slope form to find the equation of the line. Let's use the point (82, 4):
y - y1 = m(x - x1)
y - 4 = (-1/8)(x - 82)
Multiplying out the right-hand side of the equation, we have:
y - 4 = (-1/8)x + (82/8)
y - 4 = (-1/8)x + 10.25
Moving 4 to the other side to get 'y' by itself, the equation becomes: y = (-1/8)x + 10.25 + 4
This simplifies to:
y = (-1/8)x + 14.25
Converting 14.25 into quarters gives us 14.25 = 57/4. Hence the equation becomes:
y = (-1/8)x + 57/4 which matches choice A.
Final answer:
The correct equation that models the price-demand relationship is y = -1/8x + 57/4, where y is the demand in hundreds and x is the price per mini-recorder.
Explanation:
To find the equation that models the price-demand relationship, we need two points to determine the line: (x1, y1) = (82, 4) and (x2, y2) = (42, 9). The demand, y, is in hundreds of recorders and x represents the price per mini-recorder. The slope (m) of the line is given by the change in demand over the change in price: m = (y2 - y1) / (x2 - x1) = (9 - 4) / (42 - 82) = 5 / (-40) = -1/8. To find the y-intercept (b), we use one of the points and the slope in the linear equation formula y = mx + b. Using the point (82, 4), we have 4 = (-1/8)(82) + b. Solving this equation gives us b = 4 + (1/8)(82) = 4 + 10.25 = 14.25. Now the linear equation is y = -1/8x + 14.25. Since y needs to be in hundreds for the units to match the point given (400, 900), we must divide b by 100, resulting in b = 14.25 / 100 = 57/4. The final price-demand relationship is y = -1/8x + 57/4.

Part B: Which function has a greater y-intercept? Justify your answer.
Answers
3-(-1)/1-0, which then equals 4/1 which equals 4, and g(x) also has a slope of 4. So, the slopes in both functions are equal.
Part B: g(x) has a a greater y-intercept.
y=mx+b where b is the y-intercept and in the equation g(x)=4x+3, b=3 which makes 3 the y-intercept. Now, for the other function, the y-intercept is when x=0, and when x=0, f(x) (or y) equals -1 and 3>-1 so g(x) has the greater y-intercept.

Marie worked 2 weeks during her college she earned $280 the first week and 245 the second week. If 1/2 of her total earnings went to taxes and 1/4 went to college tuition how much money did she have left
Answers
Marie's total earnings for the two weeks were $525. She paid $262.5 to taxes and $131.25 to college tuition, leaving her with a balance of $131.25.
Explanation:To find out the amount left, we need to first calculate Marie's total earnings for the two weeks by adding what she earned each week. $280 for the first week plus $245 for the second week gives her a total earnings of $525.
Marie gave half of her earnings to taxes, which is 0.5 * $525 = $262.5. After that, she spent one-fourth of her earnings on college tuition, which equals 0.25 * $525 = $131.25. Summing up both amounts, we find that she spent $262.5 + $131.25 = $393.75 on taxes and tuition.
To find out the amount Marie has left, we subtract the total expenses from her total earnings. Thus, $525 - $393.75 = $131.25 is the total amount she has left after paying her taxes and tuition.

After calculating her total earnings, subtracting the amounts for taxes and tuition, Marie had $131.25 left. Her total earnings were $525. 1/2 went to taxes, and 1/4 went to tuition.
First, find her total earnings for the two weeks:
Total Earnings = $280 + $245 = $525
Next, calculate how much went to taxes. Since 1/2 of her total earnings went to taxes:
Taxes = 1/2 x $525 = $262.50
Then, calculate how much went to college tuition. Since 1/4 of her total earnings went to tuition:
College Tuition = 1/4 x $525 = $131.25
Finally, subtract the amounts for taxes and tuition from her total earnings to find out how much money she had left:
Money Left = $525 - $262.50 - $131.25 = $131.25
Marie had $131.25 left after paying taxes and college tuition.
