Answer:
There are 150 pencil crayons altogether.
Step-by-step explanation:
Given that pencil crayons are stored in boxes of 10, and there are 4 boxes of red, 3 boxes of blue, 5 boxes of green and 3 boxes of orange in the storage room, to determine how many pencil crayons are there altogether must be done the following calculation:
10 x 4 + 10 x 3 + 10 x 5 + 10 x 3 = X
40 + 30 + 50 + 30 = X
70 + 80 = X
150 = X
Therefore, there are 150 pencil crayons altogether.
