The answer is 27 yards squared
First we define variables:
x: amount of money Jack has
y: amount of money Eric has
We write the system of equations:
x = y + 80
x - 30 = 2y
Solving the system we have:
x = $130
y = $ 50
Therefore, the amount of money they had at the beginning is:
130 + 50 = $ 180
Answer:
the boys had $ 180 altogether at the beginning
