Question

David’s bowling score is 5 less than 3 times Aaron’s score. The sum of their score is 215. Find the score of each student. Write and solve an equation for this problem.

Answer 1

David's score= 160 ; Aaron's score = 55

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
