Answer 1

First off, lets start with the 20% off. Do you know how to find this?

Answer 2

20%/11

Answer 3

Close, good try though :) It would actually be 11-(20%*11), or just 11*80%. How do we convert percents into decimals?

Answer 4

8.8

Answer 5

yes! Now we need 107% of 8.8 to find the total price

Answer 6

94.16

Answer 7

That is close, what did you multiply though?

Answer 8

107*88

Answer 9

We actually need 1.07*8.8

Answer 10

9416

Answer 11

You should get 9.416

Answer 12

yea

Answer 13
