Question

The art teacher has 30 boxes of crayons with 16 crayons in each box. She gives the students 10 of the boxes to use. Explain how to find the number of crayons the art teacher has left.

Answer 1

You would have to multiply 30*16 which would give you 480 crayons because you have 30 boxes and each have 16 crayons .

Then you would multiply 16*10 because you gave them 10 boxes and they have 16 in each box which gives you an answer of 160.

You would subtract 480-160 because you started out with 480 and you gave them 160 which would mean you have 320 crayons left.

Answer 2

The art teacher has 30 boxes of 16 crayons.

16 crayons x 30 boxes = 480 crayons

She gives the students 10 of the 30 boxes, leaving her with 20.

16 crayons x 20 boxes = 320 crayons that the art teacher has left.
