An item is regularly priced at $90 . Ann bought it at a discount of 30% off the regular price. How much did Ann pay?
She would have payed $63 How I figured this is by multiply $90 by 30, and then divide it by 100, that is 27. And then you just do 90-27, and that is 63.
100-30=70
find 70% of 90
70% of 90=7/10 times 90=630/10=63
she paied $63
