It costs $13 for admission to an amusement park, plus $1.50 for each ride. if you have a total of $35.50 to spend, what is the greatest number of rides you can go in ?

U should come up with the equation 13+1.50x=35.50 
the x representing the amount of rides and the one point five represents the cost of the rides
solve the equation and it should give u the answer which should be x=15.
the amount of rides is 15 rides after paying for the entrance

In this problem situation you have three factors that give you the "guidelines" of your equation you must find in order to find the amount of the amount of rides you can go on.
Since you have to pay $13 in order it enter the amusement park, you would automatically subtract $13 from your set budget. This leaves us $22.50 as your budget.
1) 35.5-13=22.5
Now you simply divide your budget by $1.50 because you want to see how many rights you can fit in your budget.
2) 22.5/1.5=15
You can ride 15 rides with a budget of $35.50
3) 15 rides
