Question

Kelly plan to fence in her yard. The fabulous fence company charges $3.25 per foot of fencing and $15.57 an hour for labor. If Kelly needs 350 feet of fencing and the installers work a total of 6 hour installing the fence , how

much will she owe the fabulous fence company.

Answer 1

Kelly will owe $1320.92 to the fabulous fence company.

Explanation:

There is a cost related to the number of hours and a cost per feet. So the total cost is:

`T = C_(h) + C_(f)`

In which
`C_(h)` is the cost related to the number of hours and
`C_(f)` is the cost related to the number of feet.

Cost per hour

Each hour costs $15.57.

They work for 6 hours total. So

`C_(h) = 15.57*6 = 93.42`

Cost per feet

Each feet costs $3.25.

Kelly needs 350 feet. So

`C_(f) = 350*3.25 = 1137.5`

The total cost is:

`T = C_(h) + C_(f) = 93.42 + 1137.5 = 1230.92`

Kelly will owe $1320.92 to the fabulous fence company.
