Luis does chores at home to earn extra money. Each week he earns $20. He already has $320 in his savings account, and is trying to save up to buy a new iPhone X for $930. How many weeks will it be until he can buy the new iPhone?
The phone costs $930, and he already has $320 saved in his bank account so subtract 320 from 930. You will get 610. Then, you take 610 and divide it by 20 because he earns $20 a week. I hope this helped.
