Answer:
Not proportional.
Step-by-step explanation:
Let x represent number of hours and y represent total cost.
We have been given that the vista Marina rents boats for $25 per hour. In addition to the rental fee, there is a $12 charge for fuel.
The cost of rental for x hours would be [tex]25x[/tex].
The total cost of rental for x hours and fuel would be [tex]25x+12[/tex].
The equation [tex]y=25x+12[/tex] total cost of x hours.
We know that two proportional quantities are in form [tex]y=kx[/tex], where k is constant of proportionality.
We can see that our equation is in form [tex]y=kx+c[/tex] as it includes a constant 12.
Therefore, the number of hours for renting a boat is not proportional to the cost.
