Answer 1

per ounce ​(Write as a​ decimal.)

To find the unit price, we divide the total price by the total number of ounces.

For Brand G: $1.99 / 9 ounces = $0.22 per ounce

For Brand K: $3.69 / 17.2 ounces = $0.21 per ounce

For Brand P: $ / 11.8 ounces

To find the unit price after applying the coupon, we subtract the coupon amount from the total price and then divide by the total number of ounces. However, the coupon amount for Brand P is not given, so we cannot calculate the unit price for Brand P after applying the coupon.
