Question

A company held a fundraising event for a charity. Andrew contributed $25 less than twice as much as Michael. The sum of their contributions was $200. How much did Andrew contribute?

A. $75
B. $125
C. $150
D. $175

Answer 1

a = 2 m - 25

a + m = 200
eliminate m
m = 200 - a
a = 2 (200-a) -25
a = 400 - 2 a - 25
3 a = 375
a = 125
