A hand-held digital music player was marked down by 1/4 of the original price.
a. If the sales price is $128.00, what is the original price?
b. If the item was marked up by 1/2 before it was placed on the sales floor, what was that the store paid for the digital player.?
Answer:
a) The original price of music player is $170.66
b)If the item was marked up by 1/2 before it was placed on the sales floor, the store paid $213.325 for the digital player.
Step-by-step explanation:
Let the original price be x
A hand-held digital music player was marked down by 1/4 of the original price.
So, Discount = [tex]\frac{1}{4}x[/tex]
So, Sale price =[tex]x-\frac{x}{4}=\frac{3x}{4}[/tex]
We are given that the sales price is $128.00
So, [tex]\frac{3x}{4}=128[/tex]
[tex]x=\frac{128 \times 4}{3}[/tex]
[tex]x=170.66[/tex]
a) The original price of music player is $170.66
The item was marked up by 1/2 before it was placed on the sales floor.
So, Cost = [tex]170.66+\frac{1}{4} \times 170.66[/tex]
Cost = [tex]213.325[/tex]
b)If the item was marked up by 1/2 before it was placed on the sales floor, the store paid $213.325 for the digital player.

In the 2008 election,there was 28 “blue” states and 22 “red” states. Express the “red” and “blue” states as fractions, in lowest terms, of the total number of states and also in decimals.
In the 2008 election, the fractions of 'blue' and 'red' states when expressed in lowest terms were 14/25 and 11/25 respectively. In decimal form, these values are 0.56 and 0.44.
Explanation:When solving fractions in mathematics, there are straightforward steps to follow. In the context of the 2008 election with the “red” and “blue” states, this means calculating the fraction of each in relation to the total number of states which is 50 in the US. The total number of red states was 22 and the total number of blue states was 28.
To express this as fractions we utilize the simple fraction formula of Part/Whole. For the blue states, the fraction becomes 28/50. To bring this to its lowest terms divide both the numerator and the denominator by their greatest common divisor which in this case is 2, so the fraction becomes 14/25.
Similarly, for the red states, we use the fraction formula where the red states are the part (22) and the whole is all the states (50). This gives a fraction of 22/50 which simplifies to 11/25 when reduced to lowest terms.
When these fractions are expressed as decimals, 14/25 equals to 0.56 while 11/25 equals to 0.44.

There are three shelves. Each has 28 books. There is also a stack of books. There are a total of 85 books. What is the equation that represents the situation
The equation representing the total number of books, including those on three shelves and in a stack, is 84 + x = 85. By solving this equation, we find that there is 1 book in the stack.
Explanation:The question involves formulating an equation to represent the total number of books given the number of books on shelves and in a stack. Since there are three shelves each with 28 books, we first calculate the total number of books on the shelves. Then, we let x represent the number of books in the stack. The equation that represents the total number of books is:
3 shelves × 28 books per shelf + x books in the stack = 85 books total
This simplifies to:
84 + x = 85
To solve for x, we subtract 84 from both sides:
x = 85 - 84
Thus, x = 1, meaning there is 1 book in the stack.

A group of 4people share 1/2 pound of almonds how many pounds of almonds does each person get
Answer:
each person gets 1/8 pounds of almonds
Step-by-step explanation:
Four persons will divide ½ pound of almonds in four pieces, one piece for everyone, so translating this to an equation is:
X = [tex]\frac{1}{2}[/tex] ÷ 4
Where X represent how much of almonds will have everyone.
For divide fractional numbers we do a multiplication in cross, that means that the higher number in the first fraction will be multiplicated with the lowest number of the second fraction ( if the second number is not a fraction, we will assume that have a the number 1 is the lowest part) and the lowest number of the first fraction will be multiplicated with the highest number of the second number.
Then, we can rewrite the initial equation and solve as:
X= [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{4}{1}[/tex]
[tex]X=\frac{1*1}{2*4} = \frac{1}{8}[/tex]
So, each person is going to get 1/8 pounds of almonds.

A train is traveling from New Orleans to Memphis at a constant speed of 79 mph. New Orleans and Tennessee are 395.1 miles apart. How long will the train will the train take to reach Tennessee? Round to the nearest tenth.
Using the formula 'Time = Distance / Speed', the train traveling from New Orleans to Memphis at a constant speed of 79 mph would take approximately 5.0 hours to cover the distance of 395.1 miles.
Explanation:The subject of this task is about calculating travel time given a certain speed and distance. In this case, we have a train traveling from New Orleans to Memphis at a constant speed of 79 mph, and we're asked to find out how long it would take for the train to cover the distance of 395.1 miles between the two cities.
The principle used to find this is a basic mathematical concept involving time, speed, and distance, represented in this formula: Time = Distance/Speed. For this question, the distance is 395.1 miles and the speed is 79 mph.
Applying this information into the formula, the calculation becomes: Time = 395.1 miles / 79 mph = 5 hours. Rounded to the nearest tenth, the time it takes for the train to get to from New Orleans to Memphis at a constant speed of 79 mph is approximately 5.0 hours.
