Question

A fleet of vehicles is comprised of 60 vans, 20 limos, and X sedans. If 10% of all vehicles are limos, how many sedans are in the fleet?

Answer 1

Answer:

120 sedans are in the fleet.

Step-by-step explanation:

A fleet of vehicles is comprised of 60 vans, 20 limos and X sedans.

It is given that 10% of all vehicles are limos.

Let all vehicles be n

10% × n = 20

0.10n = 20

n = $\frac{20}{0.10}$

n = 200

Now we have to calculate the number of sedans.

So  60 vans + 20 limos + x sedans = 200

80 + x = 200

x = 200 - 80

x = 120

Therefore, 120 sedans are in the fleet.

Answer 2

10% of all the cars is 20 limos.

20 * 10 = 200 cars total.

limos + vans + sedans = total cars
200 cars total - 20 limos - 60 vans = x sedans

x = 120 sedans
