April, May and June are counting up the money they've saved from their weekly allowance. May has 20% less than April, and June has 20% more than May. Together, the three girls have $138. How much money
does each girl have?

Answers:

Work Shown:

x = amount April has

0.80x = amount May has

1.20*0.80x = 0.96x = amount June has

The sum of the three amounts adds to 138

(april) + (may) + (june) = 138

(x) + (0.80x) + (0.96x) = 138

2.76x = 138

x = 138/2.76

x = 50 is the amount April has

0.80x = 0.80*50 = 40 is the amount May has

0.96x = 0.96*50 = 48 is the amount June has

As a check, 50+40+48 = 90+48 = 138 to verify the answer.

Side notes:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
