If 60% of a car company's sales are from SUVs, and they sell a total of 360 cars that are not SUVs, how many SUVs did they sell?

solong [7]

Answer:

540 SUV's

Step-by-step explanation:

Sales percentage of non SUV's = 100 - 60 = 40%

Let total cars be x

40% of x = 360

$\dfrac{40}{100}*x=360\\\\\\x=360*\dfrac{100}{40}\\\\\\x = 900$

Number of SUV's = Total cars - number of non SUV's

= 900 - 360

= 540
