Question

Barry is selling magazine subscriptions for a school fundraiser. He has already sold 15 subscriptions. He plans to sell 3 subscriptions per week until he reaches a total of 30 subscriptions sold. How many weeks will it take Barry to achieve his goal.

Answer 1

Barry needs 24 months to reach 30 subscriptions. He sold 15 so far means he passed 5 weeks. 24-5 = 19 weeks he need to finish.

Answer 2

5 more weeks

Explanation:

5 more weeks if he already sold 15. 10 more weeks if you exclude the 15 he already sold.
