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

c(x) = 3 + 6x

Step-by-step explanation:

Let us assume that the ice skating rink class charges an hourly fee of $R for skating and $3 to rent skates for the day.

Now, Gillian rented skates and skates for 3 hours and was charged $21.

So, 3 + 3R = 21

⇒ 3R = 18

⇒ R = $6  per hour

Therefore, the equation represents the cost, c(x), of ice skating as a function of x. the number of hours of skating will be  

c(x) = 3 + 6x (Answer)

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
