Answer:
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.
