Answer: The answer is 432 crayons.
Step-by-step explanation: Given that a store donated 
 crayons to a day care centre. Also, each case holds 24 boxes of crayons and each box holds 8 crayons. We are to find the number of crayons that the centre receive.
In 1 box, number of crayons = 8.
So, in 24 boxes, number of crayons = 8 × 24 = 192.
Since there are 
 cases i.e., 
 cases,
 so number of crayons in 1 case = 192
and number of crayons in 
 cases 

Thus, the total number of crayons that centre receive is 432.
