Joe is saving for a new $500 bike. He currently has $125. If he saves $15 per week how long must he wait to save at least $600 to cover tax and extras. Use the variable m.

Step-by-step explanation:

Joe is saving for a new $500 bike. Joe needs to save at least $600 to cover tax and other extra expenses.

Let m represent the number of weeks that he works and saves $15.

He currently has $125. If he saves $15 per week. Therefore, the total amount of money that he has after x weeks would be

125 + 15m

Since he needs to save at least $600 to cover tax and other extra expenses, then

125 + 15m ≥ 600

15m ≥ 600 - 125

15m ≥ 475

m ≥ 475/15

m ≥ 31.6

Therefore, Joe needs to wait for at least 32 weeks to save at least $600 to cover tax and other extra expenses.
