Question

Nancy borrowed $150 from her parents to buy a video game system. She has agreed to pay them back $25 each week Which equation represents the amount of money

Nancy still owes her parents, P. after w weeks?

Answer 1

P = 150 - 25w

Explanation:

Amount borrowed = $150

Repayment amount = $25 each week

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125
