How many of the cars are NOT sedans?

Question

A local car dealer has 150 cars on the lot. 30% of the cars are sedans. How many of the cars are NOT sedans?

Answer 1

Since the problem is asking how many cars are NOT sedans, then we need to determine what number is 70% of 150 cars. This can be accomplished by multiplying 70% (in decimal form as 0.70) by 150:

70 % of 150 = 0.70 • 150 = 105

Therefore, 105 of the cars are NOT sedans.

Answer 2

Since 30% are sedans, then (100 - 30)% are not sedans, which is 70%, so multiply the total number of cars by 0.70.

0.70(150) = ?
