Answer:

D) 2x+10=40, x= 15 rides

Step-by-step explanation:

Since Paul only bought one ticket, then $10 is the constant of the equation. Since Paul pays $2 per ride, $2 will be the rate/coefficient of the equation.

Since we are solving for x, $40 will be on the right side of the equation

Putting these three facts together, we can make the equation 2x+10=40 which means D is correct
