Question

For their Summer jobs, Amanda and Julie are babysitting. Amanda starts with $250 in her savings account and Julie starts with $150 in her savings account. Since Amanda babysits more, she earns $25 per week while Julie earns $50 per week. After how many weeks will they have the same amount of money?

Answer 1

250+25x=150+50x
Subtract 150 from both sides
100+25x=50x
Subtract 25 from both sides
100=25x
Divide both sides by 25
X=4

It takes 4 weeks
