Alexa is trying to save to buy a car when she turns 16. She has $200 in her savings account now
and is saving $100 per week. Sara, however, likes to shop and has a hard time saving her
money. She is only saving $50 per week, but luckily, she has $800 already saved up in her
account right now.

16-Current age = A

A x 52 weeks in a year x 100 dollars per week + $200 in her account when 16

Ax52x100+200=Money saved up

16-Sara Age = B

B x 52 weeks in a year  x 50dollars per week + $800 in her account = money saved up when 16

Bx52x50+800=Money Saved
