The number of cars that are expected to pass through the toll booth each half-hour will be 900
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of cars that pass through the toll booth at each minute = 30
Let the number of cars to pass at each half-hour be A
1 hour = 60 minutes
half-hour = 30 minutes
So,
The number of cars to pass at each half-hour A =
The number of cars that pass through the toll booth at each minute x 30
The number of cars to pass at each half-hour A = 30 x 30
= 900 cars
Hence , The number of cars that are expected to pass through the toll booth each half-hour will be 900

a coupon takes $1 off the price so
8.97-1.00 = 7.97
they cost a total of $7.97

The Shake Shack sells large and small shakes. A large shake costs $5, and a small shake costs $3. On Sunday, the Shake Shack had a total revenue of $479. Which equation can be used to represent x, the number of small shakes sold and y, the number of large shakes sold?
479x + 479y = 15
4x + 4y = 479
5x + 3y = 479
3x + 5y = 479
Answer:
3x + 5y = 479
Step-by-step explanation:
As the problem states it, the number of small shakes will be represented by "x" and the number of large shakes will be represented by "y", so we know that the number of each mutiplied by the cost, its equal to the total revenue which is $479, so we just put that into an equation:
3x + 5y=$479
And that´s the equation that can be used to represent that inequality.

What is the rate of change for the relationship represented in the graph? (1 point)
A. 1/15
B.1/14
C.14
D.15
The rate of change for the relationship represented in the graph is 15
What is rate of change?The rate of change of a linear graph is the slope of the graph
From the graph, we have the following ordered pairs
(x,y) = (0,0) and (2,30)
So, the rate of change (m) is then calculated as:
[tex]m =\frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]m =\frac{30 - 0}{2 - 0}[/tex]
Evaluate the differences
[tex]m =\frac{30 }{2 }[/tex]
Evaluate the difference
[tex]m=15[/tex]
Hence, the rate of change is 15
