Question

I need help with this ASAP​

Answer 1

a. y = 2.5x + 5

b. $5

Explanation:

y = mx + b

m = slope is the fee per hour

b = y-intercept is the fixed fee

y = 2.5x + b

We know that she paid $15 for 4 hours, so we have point (4, 15). We now replace x and y in the equation with 4 and 15, respectively, and solve for b.

15 = 2.5(4) + b

15 = 10 + b

b = 5

a. The equation is:

y = 2.5x + 5

b. The initial fee is $5

Answer 2

a) 2.5x + 5 b) $5

Explanation:

We know that the rate is 2.50 an hour, and she parked for 4 hours. Multiply 2.5 by 4 to get 10. This means that she spent 10 out of 15 of her dollars on the rate, meaning the initial fee was 5 dollars.
