Question

Maggie earns money from working at the pet store and answering phones. She 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. Part A: Create an equation that will determine the number of hours she worked at the pet store. Part B: Solve this equation justifying each step with an algebraic property of equality. Part C: How many hours did Maggie work at the pet store last week?

Answer 1

Answer:

Step-by-step explanation:

Part A: 10x + 0.25(60) = 115

Part B: 10x + 0.25(60) = 115

                       15

                       -15           -15

           10x = 100

            /10    /10

           x   =  10

Part C: Maggie worked 10 hours last week.

x = hours Maggie worked

(60) = # of phone calls Maggie answered.
