1.The total cost in dollars to rent a cabin for x people is modeled by f(x) = 10x + 50. What is the cost for 8 people to rent the cabin?

A) $58
B) $110
C) $130
D) $145

2. Evaluate f(x) = 27 − 6x when the independent value is 5.

Respuesta :

1) f(x) = 10x + 50
f(8) = 10(8) + 50
f(8) = 80 + 50
F(8) = 130

2) f(5) = 27- 6(5)
F(5) = 27-30
F(5) = -3
Answer is C) $130
