Answer:
7 hours
Step-by-step explanation:
$21 divided by 3 equals 7 hours
Answer:
[tex]C(x)=6x+3[/tex]
Step-by-step explanation:
Rent of skates for day =$3
Gillian rented skates and skated for 3 hours and charged $21.
So, Total charge including rent = 21
So , Total charge excluding rent = 21-3=$18
So, charge for 3 hours = 18
So, Charge for 1 hour = [tex]\frac{18}{3} =6[/tex]
So, cost for x hours = 6x
So, total cost for x hours including rent = 6x +3
Let C(x) denotes the total cost
So, [tex]C(x)=6x+3[/tex]
Hence The equation represents the cost, c(x), of the ice skating as a function of x, the number of hours of skating is [tex]C(x)=6x+3[/tex]
