Problema Solution

Suppose you earn $6.15 per hour working part time at a dry cleaners. Write and solve the inequality to find how many full hours you must work to at least make $100.

Answer provided by our tutors

let 'S' represent total salary and 'h' represent total hours


S = 6.15h


to solve for how many hours you must work to make at least $100, we have S=100 and the following inequality:

100 <= 6.15h

solving for 'h' we have h >= 16.26


you must work over 16 hours in order to earn at least $100
