Daily electricity cost = $0.14 Maintenance cost per year =$24.25

Annual Percentage Rate, APR, on the credit card = 9.26%

Number of years the balance was paid off = 5 years using identical monthly payments

Sales tax = 8.22%

Required:

Lifetime total cost of the stove

2166.53

Step-by-step explanation:

Price x 1.0822 = 1067.0492 <Price with tax

P= PV x i / 1- (1+i)^-n

^ x (identical monthly payments for 5 years aka 12 x 5)

average cost for electricity x (365 x years aka 11)

cost for maintenance x 11
