Final answer:
To estimate the number of trucks needed to ship all the boxes, divide the total number of boxes by the number of boxes a truck can hold. David needs 4 trucks to ship all the boxes.
Step-by-step explanation:
To estimate the number of trucks needed to ship all the boxes, divide the total number of boxes by the number of boxes a truck can hold.
Total number of boxes: 1982
Number of boxes a truck can hold: 550
Divide 1982 by 550:
1982 ÷ 550 ≈ 3.6036
Since we can't have a fraction of a truck, round up to the nearest whole number:
Round(3.6036) = 4
Therefore, David needs 4 trucks to ship all the boxes.
