Need with a math problem

" taylor has a tortilla cart that she uses to sell tortillas at lunch. if i bought two for $9.25 each, how much would it cost me if there was 15% tax added on? "

9.25 × 2 = 18.50

so to find a percentage, you need to divide the full price by 100 and multiply that number by the percentage. so 18.50 ÷ 100= 1.85

to find 15% of 18.50 do 1.85 × 15

I'll let you crunch that ;P

The answer is 41.7 because 1.39 times 30 is 41.7
