You'll need 5 boxes

6-4

To determine the number of boxes needed for 90 pounds of pears, we need to divide the total weight of the pears by the weight a single box can hold.

Given that a box can hold seven 3-pound bags of pears, we can calculate the weight a single box can hold by multiplying the weight of a bag by the number of bags in a box. Thus, the weight a single box can hold is 3 pounds/bag * 7 bags/box = 21 pounds/box.

To find the number of boxes needed for 90 pounds of pears, we divide the total weight (90 pounds) by the weight a single box can hold (21 pounds/box):

90 pounds รท 21 pounds/box = 4.2857 boxes.

Since we cannot have a fraction of a box, we need to round up to the nearest whole number. Therefore, 5 boxes will be needed to hold 90 pounds of pears.
