I think the answers are. Number 21. is that Bobby saves 4 dollars and the new price of the top is 16. Then the answer to 22 is Sarah is saving 6 dollars and the new price is 54.
Number 23 is 10% of 400= 40 and 1% of 400= 4 and 13% of 400= 52. I hope this helps :) You get number 23's questions by first turning the percentage into a decimal then multiply the decimal by 400 and you get your answer. Also you get number 22, and 21 by turning the percentage into a decimal and then multiplying it by the number of how much it would be for the things.
