Answer:
The number of peanuts that will be needed to make all the sandwiches a child will eat by graduation is approximately 141,667 peanuts
Step-by-step explanation:
The number of peanut butter sandwiches that an average American child will eat by the time she graduates from high school = 1500 peanut butter sandwiches
The number of sandwich taken every four days = 1 sandwich
The number of peanuts required to make 18-oz jar of peanut butter = 850 peanuts
The amount of peanut butter in an average sandwich = Two ounces
Therefore, we have by the time of graduation;
Each American child will have taken 1500 sandwiches
The 1500 sandwiches will have = 1500 × 2 ounce = 3,000 ounces of peanut butter
The number of 18-oz jars of peanut butter that will contain up to 3000-oz of peanut butter = 3000-oz/(18-oz) = 166.67 Jars
The number of peanuts required to make the 166.67 Jars of peanut butter = 850 peanuts/jar × 166.67 Jars = 141666.67 ≈ 141,667 peanuts
The number of peanuts that will be needed to make all the sandwiches a child will eat by graduation ≈ 141,667 peanuts.
