Answer:

63 pickups

Step-by-step explanation:

If the ratio of cars to pickups is 4:1, then the fraction constituting cars of all of the vehicles is

4

-------- = 4/5.

4 + 1

Since there are 252 cars in the lot, and since that's 80% of the total number of vehicles in the lot, that total is 252/0.80, or 315. Of these, 20% are trucks; that comes to 0.20(315 vehicles) = 63 trucks

0.80(252 vehicles) = 202 (rounded up from the illogical 201.6)

The number of trucks is thus 0.20(252 vehicles) = 50
