Cost price of a tv is $4296,deposit is 350,balance to be paid over 24 months?

Question

determine

the amount to be paid in 24 months

hire purchase price (1 monthly installment)

amount saved if cost is paid

Answer 1

the total amount to be amortized in 24 months is:

$4296 - 350 =  $3946

at a monthly amortization payment of:

3946 / 24 = 164.42

I don't see any cost added if the tv is paid on installment.  So nothing is saved if the cost is paid outright but instead benefit is gained through installment plan.
