Question

Billy wants to hire a plumber to fix a faucet at his house. The plumber charges $125 initial fee and $85 per hour he is working.

Answer 1

85x + 125 = y

Explanation:

Let x = the amount of hours worked

Let y = the total cost to pay for this plumber

85 is the hourly pay so we multiply by the amount of hours worked to find the cost per hours. We then add that to the initial cost of 125 and we get the total cost.
