Question

Peter gets paid $20 just for accepting a yard job. He then earns $3 for every hour spent on gardening. He wants to buy a mountain bike which costs $800. How many hours does he need to work on gardening to earn enough money

Answer 1

260 hours

Explanation:

first take out the 20 fixed cost that doesn't change no matter how long he gardens from 800

divide the remainder which is 780 by 3 which is the amount he gets paid for every hour he gardens. He would have to work 260 hours for the bike if he only takes one yard job
