Question

First off how do I solve?

Answer 1

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

Step-by-step 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
