Maggie earns $10 each hour she works at the pet store and $0.25 for each phone call she answers. Maggie answered 60 phone calls and earned $115 last week

Set up an equation where c is the number of phone calls Maggie answers and h is the number of hours Maggie worked:
0.25c + 10h = 115

We're given c = 60, so we have:
0.25(60) + 10h = 115
15 + 10h = 115

We want to solve for h. So we type this equation into our search engine and we get:
h = 10
