Question

Julie needs to buy some new pencils for school. Each pencil cost 0.39. If she has 5.00 dollars now, what is the maximum number of pencils she can purchase. There is no tax in this purchase.

Answer 1

Julie will only be able to buy 12 pencils.
I did 0.39 times 12 and my answer was 4.68

Answer 2

At max, Julie can buy 12 pencils. She will have 32 cents left.

Explanation:

I did 0.39x10=3.90. Next, I did 0.30x13=5.07. I went down by one and ended up with 0.39x12=4.68.
