Answer:
Megan thinks she can fit all [tex]539[/tex] boxes into [tex]24[/tex] trucks, and her estimate incorrect as to fit all [tex]539[/tex] boxes, [tex]25[/tex] trucks are needed.
Step-by-step explanation:
It is given that each truck can hold [tex]22[/tex] boxes, and Megan needs to ship [tex]539[/tex] boxes total.
The number of trucks that can hold [tex]539[/tex] boxes will be,
[tex]\dfrac{539}{22} =24.5[/tex]
So, [tex]24[/tex] trucks will hold, [tex]22\times24=528[/tex] boxes.
To hold the remaining [tex]539-528=11[/tex] boxes, one more truck will be needed.
So, in total, [tex]25[/tex] trucks are needed to ship [tex]539[/tex] boxes.
Megan thinks she can fit all [tex]539[/tex] boxes into [tex]24[/tex] trucks, so her estimate incorrect.
