Answer by JKismyhusbandbae: 16.2
All you do is add the same number every-time.
2.7 + 2.7 to get 5.4.
8.1 + 8.1 to get 16.2
If you wanted to find y again 5.4 + 5.4 = 10.8.
35% are in display cases which means 65% are on the wall.
this means 195 cars is 65% of the collection.
to get total number of cars in the collection divide 195 by 65%
195/0.65 = 300
answer: 300 total cars
