m = minivans
p = other (what we want
p = (5/2) m or m = 2 p/5
m + p = 39
2 p/5 + 5 p/5 = 39
7 p/5 = 39
well, you are not going to get a whole number of vehicles
When Carla looked out at the school parking lot, she noticed that for every 2 minivans, there were 5 other types of vehicles. If there are 39 vehicles in the parking lot, how many of them are not minivans?
I am confused on how to solve this problem. I need help solving the problem.
