6 cars, 10 trucks, 14 SUV, 15 minivans. If 150 vehicles passed Luann, how many more minivans than cars would you expect to pass her?

150 vehicles had passed Luann.

There are:

=> 6 cars

=> 10 trucks

=> 14 SUV

=> 15 minivans.

How many minivans would we expect to pass out of 150?

=> 6 + 10 + 14 + 15 = 45

=> 15 / 45 = x / 150, where 15 is the number of minivans, and 45 is the total number of vehicles that passed

=> 150 / 45 = 3.333333 ... repeating decimals

=> 3.333 ... * 15 = 50

Thus, x = 50, there will be 50 minivans that will pass in LUann
