Answer:
David's score= 160 ; Aaron's score = 55
Step-by-step explanation:
let Aaron's score be 'x'.
so, David's score will be 3x - 5
(3x - 5) + x = 215
3x + x - 5 = 215
4x = 215 + 5
4x = 220
x = 220/4
x = 55
therefore, Aaron's score = 55
David's score is (3x - 5) = (3*55) - 5 = 165 - 5 = 160
To find the amount of money you pay for tax, you have to multiply the price of the product by the percentage of the tax, then divide it by 100. in this case, 76x5.6=425.6/100=4.256 which is $4.26 (to the nearest cent)
