Answer:
For 45 guests, Nathan should order:
21.6 (or 22) pieces of Fried Chicken
3.3 pounds of Deli Meat
9.675 pounds of Lasagna
Explanation:
The information given for each food item is based on 25 people. If Nathan is going to have 45 guests and plans to only count them as 'half a guest', then we can first take the total number of guests and divide by 2: 45 ÷ 2 = 22.5. Since the original amounts are based on 25 people, we need to find the percentage of food needed for only 22.5 people: 22.5 ÷ 25 = 0.9 x 100 = 90%. Since Nathan will only need 90% of the food totals given, we can find how much he should order by multiplying each food amount by 90% or 0.9:
24 x 0.9 = 21.6 or 22 pieces of Fried Chicken assuming you can't buy partial pieces of chicken
3 2/3 or 11/3 x 0.9 = 3.3 pounds of Deli Meats
10 3/4 or 10.75 x 0.9 = 9.675 pounds of Lasagna
