Answer 1

0.7125*P

The original price of a product is P.

The products are marked down 25%, so the sale price of the products are

75% of P = 0.75*P

Then, in the check out, the store offers a coupon for 5% off, so the sale price will decrease 5%, that is, will be multiplied by 0.95:

Final price = 0.75*P * 0.95 = 0.7125*P
