Question

if Karrlo starts with 45 stamps and collects an additional 7 stamps per week, how many weeks will it take for Karrlo to collect 129 stamps? (pls write it out in an equation, thanks)

Answer 1

Answer: It will take Sarah 12 weeks to get 129 stamps total in her collection.

If you subtract 129 from 45 you get 84. If you then divide 84 by 7 you get 12.

If this answer is incorrect I am very sorry to have bothered you.
