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.

What's the banana worth?

Answers

Answer:

5!

Step-by-step explanation:

Looking at the first one, you have three watermelons. 36/3 is 12, so one watermelon is worth 12!

With the second one, you subtract 12 from 28 to get 16. Since there are two (peaches?), you divide 16 by two to get the peaches worth, which is 8.

That leaves you with the last one. I used the simple "8 - __ = 3", which got me the answer, 5.
