Answer:
28.58 pounds, about 29 pounds
Step-by-step explanation:
Poultry meat with bones ; divide number to be served by 2.5
Meat with little or no bone ; divide number to be served by 3.5
If number of guests to be served = 100
Meat served = 100

Answer:
3,160,080
Step-by-step explanation:
- The first place can be taken by any one of the 22 students.
- The second place can be taken by any one of the remaining 21 students.
- The third place can be taken by any one of the remaining 20 students.
- The fourth place can be taken by any one of the remaining 19 students.
- The fifth place can be taken by any one of the remaining 18 students.
<em>This basically means multiplying 22, 21, 20, 19, and 18. Or, the number of permutation of 22 things taken 5 at a time.</em>
The answer is 22*21*20*19*18 = 3,160,080
<em>Using formula
</em>
