Question

Krista bought the same number of pencils and erasers with $252. Each eraser costs $18. How many erasers did she purchase?

Answer 1

14 erasers.

Explanation:

Just simple division!

252/18=14

Answer 2

7 erasers

Explanation:

Since we know that she bought the same exact amount of pencils and erasers, we can assume that they are the same price. So, to find how many things she can purchase, divide 252 by 18, which will give you 14.

Then, since she bought the same number of pencils and erasers, divide 14 by 2, which is 7. So, Krista bought 7 pencils and 7 erasers.

You can check your work by multiplying 7 by 18 and adding that to 7 multiplied by 18. You'll get 252, which is the amount Krista started with.

Hope this helps! :)
