The initial cost is $45. To determine the increase, you need to follow two steps.

First you have to find what 7% of the original $45 is. This will tell us how much the cost will increase by.
To find 7% of $45, you need to multiply .07 x 45 = 3.15
This tells us that 7% of $45 = $3.15

Next, you have to add the increase to the original cost. This will be the new monthly cost.
$45 + $3.15 = $48.15

Based on the graph, what is the initial value of the linear relationship?
Fofino [41]

The initial value of the linear relationship is 5.

Solution:

  • The y-intercept is the point where the line crosses at y-axis.
  • The initial value of the linear function is the y-intercept.

On observing the graph, the line crosses y-axis at the point (0, 5).

So, y-intercept = 5

That is initial value = 5

Therefore the initial value of the linear relationship is 5.

11Alexandr11 [23.1K]

Answer: 56 large cars and 86 small cars.

Step-by-step explanation:

Let's call:

l: the number of large cars.

s: the number of small cars.

Then, you can set up the following system of equations:

\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.

You can use the Elimination Method:

- Multiply the first equation by -4.0

- Add both equations.

- Solve for l.

\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5

l≈56

Substitute l=56 into one of the original equations and solve for <em>s:</em>

<em> </em>56+s=142\\s=142-56\\s=86
