Question

heidi and her family took a vacation. heidi placed the hotel room charge of $689 on her credit card. she paid the minimum of $20 a month for 49 months. at an interest rate of 18%, she paid $287.90 in interest. how much did heidi spend on the hotel room? $

Explanation:

Step1: Calculate total payments

Total payments = Monthly payment × Months = $20 × 49 = $980

Step2: Adjust for overpayment

Total spent = Total payments - Overpayment = $980 - $3.10 = $976.90

Wait, correction: The interest is $287.90, so total spent is principal + interest = $689 + $287.90 = $976.90 (since total payments equal principal plus interest, and the overpayment is a result of rounding in monthly payments). The direct way is principal plus interest.

Step1: Identify principal and interest

Principal = $689, Interest = $287.90

Step2: Calculate total spent

Total = Principal + Interest = $689 + $287.90 = $976.90

Answer:

976.90
