A total of 40 dollars is to be divided between Abbott and Costello, with Costello to receive 12 dollars more than Abbott. How much will each receive?
Solution:
Costello = 12 + x
Abbott = x
x + x + 12 = 40
2x + 12 = 40
2x = 40 - 12
2x = 28
x = 28 ÷ 2
x = 14
Abbott will receive 14 dollars.
Costello will receive 12 more than Abbott for a sum of 26 dollars.
PROVE:
Abbott + Costello = 40
14 + 26 = 40
40 = 40...It checks to be true.
What do you say?
