Answer:
Kelly will owe $1320.92 to the fabulous fence company.
Step-by-step explanation:
There is a cost related to the number of hours and a cost per feet. So the total cost is:
[tex]T = C_{h} + C_{f}[/tex]
In which [tex]C_{h}[/tex] is the cost related to the number of hours and [tex]C_{f}[/tex] is the cost related to the number of feet.
Cost per hour
Each hour costs $15.57.
They work for 6 hours total. So
[tex]C_{h} = 15.57*6 = 93.42[/tex]
Cost per feet
Each feet costs $3.25.
Kelly needs 350 feet. So
[tex]C_{f} = 350*3.25 = 1137.5[/tex]
The total cost is:
[tex]T = C_{h} + C_{f} = 93.42 + 1137.5 = 1230.92[/tex]
Kelly will owe $1320.92 to the fabulous fence company.
