Question

Aubrey has can spend at most $100 more on her credit card. She brought a pair of shorts for $20, and sees a sale for t-shirts $15 per shirt. How many t-shirts can Aubrey buy with her $100 budget? Which of the following equations fits this situation?

A) 20x +15_<100

B) 15x +20_>100

C) 15x +20 _<100

Answer 1

Since Audrey only has $100 available and each t-shirt costs $15 with $20 already spent on shorts, the correct choice would be c.

Also the choices are actually INEQUALITIES rather than equations.
