SOLUTION

Using the units able the area of the farm land is

[tex]\begin{gathered} \frac{3}{1.61}\times\frac{2.5}{1.61} \\ =2.89 \end{gathered}[/tex]

Therefore the area of the farmland is 2.89 square mile

The number of truckload needed is:

[tex]\frac{2.89}{0.8}=3.61[/tex]

Therefore the whole load of truckload is needed is 4

Total cost is

[tex]\begin{gathered} 4\times\$65.18 \\ =\$260.72 \end{gathered}[/tex]
