Use estimation and mental computation to solve the following question. Grandfather is hosting a crawfish boil for his family reunion, 49 people are expected to come . Grandfather can buy live crawfish in 50 lb bags. In the past, 46 people ate 49lbs of crawfish. How much crawfish will each person eat and how many 50lb bags should he buy?
To estimate the amount of crawfish each person will eat, we can divide the total weight of crawfish eaten in the past (49 lbs) by the total number of people that ate it (46 people).
49 lbs / 46 people ≈ 1.06 lbs/person
Therefore, each person is estimated to eat about 1.06 pounds of crawfish.
To estimate the number of 50 lb bags Grandfather should buy, we can divide the total number of people expected to come (49 people) by the number of people estimated to eat 1 bag (46 people).
49 people / 46 people ≈ 1.07 bags
Therefore, Grandfather should estimate purchasing about 1.07 bags of crawfish.
