If 85 pounds of seed are needed to plant a 10-acre field, then each pound can cover
[tex]\frac{10}{85}\text{acres per pound.}[/tex]
Computing the above division, we get:
[tex]0.12\text{ acres per pound.}[/tex]
Now, in the second problem, the rent for 3 hours is $10, therefore, the cost per hour is:
[tex]\frac{10}{3}\text{dollars per hour.}[/tex]
The decimal form of the above solution is:
[tex]3.33\text{ dollars per hour.}[/tex]
Answer:
a)
[tex]0.12\text{ acres.}[/tex]
b)
[tex]3.33\text{ dollars per hour.}[/tex]
