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?

Answer 1

Answer:

The cost without the coupon is $20

Answer 2

Answer:

$20

Step-by-step explanation:

So the 4 dollar is 20% of the original price of the dog food . Lets have x be the original price of the dog food

4=x*.20

So we need to get x alone so we need to divide both sides by .20

4/.20=(x*.20)/.20

The two .20s on the side with the x cancel each other out so we can remove those

4/.20=x

now just divide 4/.20

20=x

So the original price is $20
