Question

A plumber charges $25 to come to a home, and $50 per hour for a repair. Which equation gives the total cost, y, for a repair that lasts x hours
a) 15x-25=y
b) 15x+25=y
c) 25x-15=y
d) 25x+15=y

Answer 1

Answer:

The total cost is given by equation

y = 25 + 50 x

Where y  represents the total cost and x represents the hours he worked.

Step-by-step explanation:

Given : A plumber charges $25 to come to a home, and $50 per hour for a repair.

We have to determine the equation gives the total cost, y, for a repair that lasts x hours.

Since, given y represents the total cost

and x represents the hours he worked.

also, he charges $25 to come to a home,

and $50 per hour for a repair.

so , for x hours he charge 50 x

Thus, The total cost is given by equation

y = 25 + 50 x

Answer 2

The answer is b)

15*x+25=y
