After x weeks:

Jules will have: 1,200 + 40 x.

Kelsey will have: 400 + 50 x.

If we want to know in how many weeks will they have the same amount of money, we will make an equation:

400 + 50 x = 1,200 + 40 x

50 x - 40 x = 1,200 - 400

10 x = 800

x = 800 : 10

x = 80

Answer: In 80 weeks they will have the same amount of money.
