A motor car advertised for $6990 is sold under the following terms: 40% deposit and the balance repaid over 5 years at $32 per week.

A. What is the deposit required?

B. Find the amount paid as interest?

The deposit required is 40% ... so thats 40% of 6990

0.40 (6990) = $ 2796 < = = the deposit

that leaves 6990 - 2796 = $ 4194

balance repaid over 5 years at $ 32 per week ...

1 yr = 52 weeks ... so 5 years = 5 (52) = 260 weeks

at $ 32 per week ... 260 * 32 = $ 8320

so if he is paying back $ 8320 ... and he owes $ 4194 ... then the interest paid is 8320 - 4194 = $ 4126 < = = I am not 100% sure on this one ... it just seems to make sense ... but I am not the best at financial math problems
