Answer:
60 cars
Step-by-step explanation:
In order to find how many total cars are in the parking lot, you must use a ratio. This is what you know:
25% = SUVs
40% = pickups
X% = cars
100% - (25% + 40%) = 35%. Thus, the remaining 35% of the cars are sedans. Now, we use a ratio to find the TOTAL number vehicles. See below:
X/65% * 21/35% = 35x = (21x65) = 1,365 (Hint: remember cross-multiplying??)
35x = 1,365
x = 1,365/35
x = 60 total cars
Sanity check:
25% of 60 = 15 SUVs
40% of 60 = 24 pickups
35% of 60 = 21 sedans
TOTAL: 60 cars
