Question

Erica wants to buy a new dishwasher that costs $500. She has already saved $100. She earns $1,200 a month and her total monthly expenses come to $1,000. Erica is going to put all of her extra money each month into her savings account for the dishwasher. Assuming her expenses stay the same, how long will it take Erica to save enough money for the dishwasher?
A
three months

B
two months

C
five months

D
one month

Answer 1

2 months. She already has $100 saved which means she needs $400 more. Each month, she spends $1000 out of $1200 which means she has $200 left each month. $200 for 2 months will give her the $400 she needs.
