Several items in a store are on sale. Complete the table with the correct prices.

Answers

Answer:

1.$36

2.$35

3.$51

4.$43

Answer:

1.) $35

2.) $36

3.)$51

4.)$43

Step-by-step explanation:

1.)30% of 50 is 15 and you would subtract the 15 from 50 to get your discount.

2.)55% of 80 is 44 and you would subtract 44 from 80 to get your after price.

3.)For this one, I divided the discount price by 3 and multiplied it by 4 to get the original price since 1/4 was taken from it or 25%.

4.) There was only one option left.
