A ride on a roller coaster cost 4 tickets while the boat ride onlycost 3 tickets Michael went on the two rides a total of ten times and spent a total of 37 tickets

One equation that represents this statement above me could be: 4r + 3 (10-r) = 37.

How? R = Rollercoaster - B = Boat Rides

r + b = 10

37 tickets were spent so ...

4*r + 3*b = 37

We just multiplied the number of rides on roller coasters and the boats with the price of both.

Now we have to express boat rides from the first equation:

b = 10-r, and express that in the second equation, now we get:

4r + 3 (10-r) = 37, which is the answer.
