Problema Solution

Together, Devin, Jennifer, and Alex earned a total of $450 by washing cars. Each earned a different amount. However, they agreed to share equally. Jennifer gave a fourth of her money to Alex, but then Alex had too much so he gave $30 to Devin and they all had the same amount. How much did each earn originally

Answer provided by our tutors

Let Devin's income be x, Jennifer's y and Alex's z.

The equations are,

x+y+z=450

y/4 + z - 30 = y-y/4

x+30=y-y/4

Solving,

x=120

y=200

z=130
