Question

A painter earns $15 per hour. What is the minimum number of hours he must work to earn at least $200? Write an inequality to represent this situation and solve. Show your work.

Answer 1

Let x be the number of hours.
Our inequality needs to be greater than or equal to $200.
15x >= 200
x >= 200/15
x >= 13 1/3

So if he gets paid for complete hours, minimum number of hours he must work is 14.
