Respuesta :
c(x) = 6x + 3
$6 per hr..and $3 for the skates
check..
c(x) = 6x + 3
he skated for 3 hrs and was charged $21
c(3) = 6(3) + 3
c(3) = 18 + 3
c(3) = 21
.so it is c(x) = 6x + 3

Answer:
The equation represents the cost, c(x), of ice skating as a function of x is [tex]c(x)=6x+3[/tex].
Step-by-step explanation:
Consider the provided information.
Let R be the per hour rate of the using the skating rink.
It is provided that $3 is the rent of skates for the day.
If Gillian rented skated and paid $21 after 3 hours of skating, this can be represented as:
[tex]21=3R+3[/tex]
[tex]3R=18[/tex]
[tex]R=\frac{18}{3}=6[/tex]
Therefore, the hourly fee for skating is $6.
Now, write the equation represents the cost c(x) of the ice skating as a function of x.
Total cost = Number of hours × Hourly fee + Rent skates for the day.
Replace total cost with c(x), Number of hours with x, Hourly fee with 6 and rent skates of the day with 3.
Thus the required equation is:
[tex]c(x)=6x+3[/tex]
Thus, the equation represents the cost, c(x), of ice skating as a function of x is [tex]c(x)=6x+3[/tex].
