Answer 1

Mrs.Solar modeled Contractor 2's fees with the formula y = 150 + 55x. Mrs.Solar compared to Contractor 2's fee to Contractor 1's fee.

(A) What does the difference between 50 and 55 mean in the real-world context?

(B) what does the difference between 200 and 150 mean in the real-world context?

Answer 2

I take that formula for Contractor 1's fees is \(y = 200+50x\)?

For part A, you could say that it means for each x, Contractor 1's fees grow 50 and Contractor 2's fees grow 55. (slope)

For part B, you could say that at x=0 (initial), Contractor 1's fees are 200 and Contractor 2's fees are 150. (y-intercept)

Answer 3

i took it as like 150 and 200 were the baseline cost of the contractors and the 50 and 55 maybe being the cost per hour he/she works?
