Question

Alexis bought 50 collectible stamps at a garage sale. Each week, she purchases 30 stamps to add to her

collection. How many weeks will she need to purchase stamps to have more than 500 stamps?

Answer 1

14 (exactly 500) or 15 (over 500)

Explanation:

We know that Alexis has already bought 50 stamps.

50 + 30 = 80

We need to subtract to see how many stamps she needs.

500 - 80 = 420

We divide by 30 to see about how many weeks it would take.

420 / 30 = 14

We can add 1 more week because she wants to have more than 500 stamps.

hope this helps :)
