Geo has $145 in his savings account. He earns $36 a week mowing lawns. If Geo saves all of his earnings, after how many weeks will he have $433 saved?
Geo already has $145 in his savings account. Let's see how much more money he needs to reach a total of $433.
Required amount = $433 (goal) - $145 (current savings)
Required amount = $288
Now, to find out how many weeks he needs to save $288 while earning $36 per week, we do the following:
Number of weeks = Required amount / Weekly earnings
Number of weeks = $288 / $36
Number of weeks = 8
So, it will take Geo 8 weeks of saving his earnings to reach $433 if he saves all of his $36 weekly earnings.
