Answer:
We can start by calculating the total amount of money earned per week:
$12.50/hour x 25 hours/week = $312.50/week
To find out how many weeks it will take to earn $3,437.50, we can set up a proportion:
Total amount earned / Amount earned per week = Number of weeks
$3,437.50 / $312.50/week = 11 weeks
Therefore, it will take 11 weeks to earn $3,437.50 working 25 hours per week at a rate of $12.50 per hour.
