Ruby set a goal of saving at least $200 in a savings account.

She currently has $60 in the account. If she invests $5 of her weekly allowance per week, how many weeks will it take her to reach her goal?

Define the variable.

• let x = Ruby

• let x = the number of weeks to reach her goal

• let x = her monthly allowance

• let x = her savings account
