Question

Patricia bought a new swimsuit that cost $35 before taxes sales tax is 7.5% how much did Patricia pay including sales tax

Answer 1

You are finding 7.5% of 35$ so 7.5/100 *35/1=2.625. Then, you add that to the 35$ giving you $37.625. But, since money is rounded to the nearest hundred, you pay $37.63.
