Answer:

In 4 four weeks, they'll have the same amount of money

Explanation:

1. Ann: y=5x+20; Sue: y=10x

2. You have to set both equations equal to each other so, 5x+20=10x. Solve for x. Take 5x away from each side, 20=5x. Divide both sides by 5, 4=x.

With the equations, you can graph and where the two lines meet is where they'll have the same amount of money.
