Question 904595: I am trying to express the total cost of installation of cable as a function C(x) of x. The connection box is 5 miles from where the road turns down the driveway. It costs $100 per mile to run along the highway. The driveway to the house is 2 miles long. The cost for installing cable off the highway is $140. X represents the distance in miles that the cable runs along the highway from the connection box before turning off towards the house. I understand that the function needs to represent 100x+140 x to equal the total cost but C(x) not not equal 110x+140x. Thank you

c(x)=100*h+140*o
c(x)=100*5+140*2
c(x)=500+280
c(x)=780
