The after school craft center has 15 boxes of 64 crayons each. In 12 of the boxes , 28 of the crayons have not been used. All the rest have been used how many of the crayons in the center have been used?
12 boxes of 28 crayons have been usedÂ
so 28x12=336
336 crayons have been used
Hope this helped! :))
The correct answer is:
624 crayons.
Explanation:
In 12 of the boxes, 28 crayons have not been used; this leaves 64-28=36 crayons that have been used. 12(36) = 432 crayons have been used in these boxes.
3 full boxes have been used; this is 3(64) = 192 crayons.
Together this makes 432+192 = 624 crayons that have been used.
