Problema Solution
If I have 4 times the amount of money as you, and I then give you $33, you now have 3 times the amount of money as me. How much money did each of us start with?
Answer provided by our tutors
let
x = the money I start with
y = the money you start with
I have 4 times the amount of money as you:
x = 4y
I then give you $33, you now have 3 times the amount of money as me:
y + 33 = 3(x - 33)
by solving the system of equations:
x = 4y
y + 33 = 3(x - 33)
we find:
x = $48
y = $12
