Question

It costs $23 per hour plus a flat fee of $16 for a plumber to make a house call. What is the equation of the form y = mx + b for this situation? A) y = 16x B) y = 23x C) y = 16x + 23 D) y = 23x + 16

Answer 1

It is D 100%

Explanation:

Answer 2

D is the best choice because y would be the total amount of money he would have to pay. X would be the amount of hours he uses the phone and the hourly fee is 23 so it would be 23x. the flat fee was 16 so you just add that on to the hourly fee. The whole equation should be y = 23x + 16
