1. together they can save $130 per week
2. Freddie can save 3 times more than Caue
3. Austin can save 10 dollars less than Freddie 

    Form an equation and then solve it to find how far each person can save.

Answer 1

F+C+A = 130

F=3C. or C=F/3

A = F-10

F+F/3 +F-10 = 130

7F/3 = 140

F = (3/7)(140) = $60 for Freddie

A = $50 for Austin

C= $20 for Caue
