Answer:
Total Finance cost $ 517
Explanation:
Down payment paid = 15 % of $ 2650
= (15 / 100 ) * 2650
= $ 397.5
Amount left to be paid = $2650 - $ 397.5
= $ 2252.5
Since antoni gaudi purchase with an installment loan that has an APR of 12%
Monthly payment =

r = 12 % = 0.12
n = 42
Putting values we get,
Monthly Payment =

Monthly payment = 65.94
Since payments are for 42 months so,
Total payments = 42 * 65.94
= $ 2769.48
Total Finance cost = Total payments - Amount left to be paid
= 2769.48 - 2252.5
= 516.98
=~ $ 517
