14. what is the purpose of using coupons?\na. to avoid paying sales tax\nb. to extend the warranty period\nc. to reduce the cost of goods at the time of sale\nd. to increase the price of goods
Answer
Brief Explanations:
Coupons are used to give consumers a discount. This discount reduces the cost they pay for goods at the time of purchase. Sales tax is calculated on the discounted (coupon - adjusted) price in most cases, so coupons don't avoid sales tax. They have nothing to do with warranty periods. And their purpose is to reduce, not increase, the price of goods.
Answer:
C. To reduce the cost of goods at the time of sale
