Ricardo has $25 to spend on school supplies he spends 72% of the money on a backpack and the rest on a large binder. how much does he spent on the backpack? how much does he spend on the binder?

$18 on Backpack $7 on binder. if you turn the percent into a decimal .72 and multiply .72 by 25 you get 18 which is the cost of the backpack. subtract 18 from 25 and you get $7 left meaning the binder was $7
