Answer:
65 months
Explanation:
Data provided in the question:
Limit of the credit card = $1,000
Cost of the new CD player and speakers = $975
Minimum monthly payment made by Katsumi = $15
Now,
since there are no finance charges charged,
therefore,
the net payment that has to be made is $975
Therefore,
Months needed to pay off the rate
= [ Net payment amount ] ÷ [ Minimum monthly payment ]
= $975 ÷ $15 per month
= 65 months
