katia makes crafts using glass jars She can buy packages of 12 jars for $9 how many jars can kitia buy with $45
ale4655 [162]

Hello!

If Katia can buy packages of jars for $9, we can determine how many packages she can purchase with $45 by using the formula:

45/9 = 5

We divide the total number of money that she has by the amount of money one package of jars costs. Now, the question also asks how many jars she can buy, not just how many packages.

We know that she can buy 5 packages, and that there are 12 jars in each package. To find the total number of jars she can buy, we will multiply 5 by 12.

5 x 12 = 60

Katia can buy 60 jars with $45.

I hope this helps you! Have a lovely day!
