Question

Travis owes Mickie $120. Each week he pays her $7. Which is an equation that describes the amount (A) that Travis owes after (W) weeks

Answer 1

120 - (W*7)= A

Explanation:

Let's say after 3 weeks. $120 is what he owes her in the beginning. He pays her $7/week.

After 3 weeks, he owes her 120 - (W*7)= A.

W=3, since we are 3 weeks along. So, after 3 weeks he still owes her

120 - (3*7)= A >>> 120 - 21= A >>> 99= A.
