1st option: If both car dealers sold 50 cars. Dealer B sold 4 more hybrid cars.

1) Based on what we were told: "12%of the cars sold by Car Dealer A were hybrid cars. 20% of the cars sold by Car Dealer B were hybrids." We can analyze the following alternatives to check whether this is right or wrong, true or false.

2) If both car dealers sold 50 cars. Dealer B sold 4 more hybrid cars.

Let's check both Dealers:

12% of 50 =0.12 x50 =6 and 20% of 50 = 0.2 x 50 = 10

10-6 =4


\begin{gathered} A)0.12*50=6 \\ B)0.2*50=10 \\ True \\ \\ \end{gathered}

Since we're dealing with a universe of 50 cars. Then this is true. The other choices we can't state without more information or are false.
