You buy a wedding gown for $2,999, plus sales tax of 7.5%. The retailer finances the entire amount (including the sales tax) for 3 years and says you will be charged 12% interest. However, the retailer uses the add-on method. Calculate your monthly payment.
a. |
$121.79 |
|
b. |
$107.08 |
|
c. |
$99.61 |
|
d. |
$106.02 |
Cost of Gown = $2999
Sales Tax = 7.5% * $2999 = $224.93
Total Cost of Gown = $2999 + $224.93 = $3223.93
As per add on method of interest, total interest is calculated as simple interest on starting loan amount for the entire duration
i.e. interest using add on method = P * r * t (P is Principal, r is rate of interest & t is time)
Total interest using add on method = $3223.93 * 12% * 3 = $1160.61
Hence total amount of repayment = $3223.93 + $1160.61 = $4384.54
Monthly payment = $4384.54/(3*12) = $4384.54/36 = $121.79
