An amusement park charges a fee of 5$ each time you enter the park .The cost of each ride is 2.50.Which expression shows the cost C (in dollars) as a function of the number of rides r you go on at the amusement park during one visit

C(r) = 5 + 2.5r

Step-by-step explanation:

An amusement park charges a fee of 5$ each time you enter the park. The cost of each ride is $2.50.

Therefore, the cost of r number of rides inside the park will be $2.5r.

Hence, the expression that shows the cost C (in dollars) as a function of the number of rides r, I go on at the amusement park during one visit will be  

C(r) = 5 + 2.5r (Answer)

No solution
Step-by-step explanation:
Simplify the left side.
− 3 x − 10 =3 ( 3 − x )
Simplify  
3 ( 3 − x ).
− 3 x − 10 = 9 − 3 x
Move all terms containing  x  to the left side of the equation.
− 10 = 9
Since  
− 10 ≠ 9  , there are no solutions.
No solution
