It would be least expensive to purchase goods with installment credit.
Step-by-step explanation:
Buying goods would be least expensive if a person buys with installment credit because it will break your payment amount into the several installments (monthly installments) for a certain period of time. The term of this installment can be for one month and maximum for 30 years.
A buyer doesn’t need to pay the whole amount at time of shopping. Installment credit helps build in the credit power of the buyer. Installment loans were first used by the Singer Company in 1850 to finance the purchase of their sewing machines.
