Question

By using the 20 percent off coupon that she found in the newspaper, Jill saved $4 on the extra large bag of dog food that she bought. What was the cost of the bag of dog food without the coupon?

A. $8
B. $12
C. $16
D. $20

Answer 1

By calculating 20 percent of the original price of the dog food bag and setting it equal to the $4 saved, we find that the original cost before the coupon was $20.

Step-by-step explanation:

If Jill saved $4 using a 20 percent off coupon on the bag of dog food, we can determine the original price before the discount. To do this, we consider that 20 percent of the original price equals the amount saved, which is $4. To find the original price, we can set up the equation 0.20 × original price = $4. By dividing both sides by 0.20, we get the original price = $4 / 0.20, which equals $20. Therefore, the cost of the bag of dog food without the coupon was $20.
