At an airport, its costs $7 to park for up to one hour and $5 per hour for each additional hour. let x represent the number of hours parked. write a function that models the cost, c(x), of parking x hours, where x is an integer greater than 1. a: c(x)=5x+12 b: c(x)=5(x+1)+7 c: c(x)=5(x-1)+7 d: c(x)=5x+7

At an airport, its costs $7 to park for up to one hour and $5 per hour for each additional hour. let x represent the number of hours parked. write a function that models the cost, c(x), of parking x hours, where x is an integer greater than 1. a: c(x)=5x+12 b: c(x)=5(x+1)+7 c: c(x)=5(x-1)+7 d: c(x)=5x+7

THIS IS THE BEST ANSWER 👇

C: C (X) = 5 (x-1) +7

because x-1 shows that the first hour costs $ 7 and then x 5 shows the fact that $ 5 every hour thereafter costs $ 5
