The ice skating rink charges an hourly fee for skating and $3 to rent skates for the day. Gillian rented skates and skated for 3 hours and was charged $21. Which equation represents the cost, c(x), of ice skating as a function of x, the number of hours of skating?

c(x) = 3x + 3
c(x) = 6x + 3
c(x) = 7x + 3
c(x) = 8x + 3

Respuesta :

Answer:

c(x) = 6x + 3

Step-by-step explanation:

c(x) = 6x + 3

he skated for 3 hrs and was charged $21

c(3) = 6(3) + c(3) = 18 + 3

c(3) = 21

correct....so it is c(x) = 6x + 3

answer:

B) c(x) = 6x + 3

explanation:

Gillian rented skates, which costs $3. Now you must subtract that from your total as the next step is to find how much the hourly fee for skating is. $21 - $3 = $18. $18 was the total price for three hours of skating so to find how much the hourly rate is, you divide it by 3. $18/3 = 6. Therefore it is $6 per x amount of hour(s) plus $3 for skates, or simply put, c(x) = 6x +3.
