Monique bought a shirt for $22.80 during a 30% off sale. How much does the shirt cost when it is not on sale?

22.80/100%?/30%

Step-by-step explanation:

100/10=10*3 = 30 %

22.8/10=2.28*3=6.84

22.80-6.84=15.96

$ 15.96 But with out the discount it cost and adding 30 % to the price it will be $29.64.

I kinda did something wrong that i didn't notice.

29.64

Step-by-step explanation:

First we multiply 0.3 with 22.8. This will give us 6.84 which is the 30% off. Now we add 22.80 and 6.84 and we will get our answer 29.64.
