Answer:
Explanation:
To solve this problem, we can use the following formula:
Total amount of money = Amount saved + Amount earned per week * Number of weeks
We want to find the number of weeks, so we can rearrange the formula to solve for Number of weeks:
Number of weeks = (Total amount of money - Amount saved) / Amount earned per week
Substituting the values we have:
Number of weeks = ($250 - $45) / $20
Number of weeks = $205 / $20
Number of weeks = 10.25
Therefore, it will take Wendell 10.25 weeks to have enough money to buy a new tennis racket.
