Answer:
3 boxes.
Step-by-step explanation:
Let x represent number of 1.2 pounds boxes.
We have been given that Mr. Smith has 15.6 pounds of oranges to pack for shipment. He can ship 2.4 pounds of oranges in a large box and 1.2 pounds in a small box.
The oranges covered in x small boxes would be [tex]1.2x[/tex]
Oranges packed in 5 large boxes would be [tex]5\times 2.4\text{ pounds}=12\text{ pounds}[/tex].
We can represent our given information in an equation as:
[tex]1.2x+12=15.6[/tex]
[tex]1.2x+12-12=15.6-12[/tex]
[tex]1.2x=3.6[/tex]
[tex]\frac{1.2x}{1.2}=\frac{3.6}{1.2}[/tex]
[tex]x=3[/tex]
Therefore, the minimum number of small boxes required to ship the rest of the oranges would be 3 boxes.
