They have 40 guests for the graduation party
And 35 drop-in guests
The drop-in guest = 1/2 guest
Then the total number of guests = 40 + 1/2 x 35 = 57 1/2
The table gave the amount of 23 guests
We need for 57 1/2, then we must order from each item 3 times
Because 23 + 23 = 46 less than the guests, then 46 + 23 = 69 more than the gustes
Since the number of the fried chickens is 24 pieces
Then they should order 24 x 3 = 72 pieces
