if you have 6 cars, 10 trucks, 14 suv, 15 minivan, at this rate how many trucks would pass luann if 90 vehicles passed her. show your work

Answer 1

There would be 20 trucks.

6 + 10 + 14 + 15 = 45

6 + 10 + 14 + 15 = 45

45 + 45 = 90

I basically doubles the amount, but in this case, the different vehicles pass Luann twice in a row. So, 20 trucks passed her.

I hope this helps! :)

Answer 2

20
