Question

Answer each part. If necessary round to the nearest hundredth

Answer 1

0.12 acres
3.33 dollars per hour

Answer 2

If 85 pounds of seed are needed to plant a 10-acre field, then each pound can cover

`(10)/(85)\text{acres per pound.}`

Computing the above division, we get:

`0.12\text{ acres per pound.}`

Now, in the second problem, the rent for 3 hours is $10, therefore, the cost per hour is:

`(10)/(3)\text{dollars per hour.}`

The decimal form of the above solution is:

`3.33\text{ dollars per hour.}`

Answer:

a)

`0.12\text{ acres.}`

b)

`3.33\text{ dollars per hour.}`
