30% of the cars sold by car dealer a were blue. 50% of the cars sold by car dealer b were blue. which statement must be true?
if both dealers sold the same number of cars, car dealer b sold 20 more blue cars.
car dealer b sold more blue cars than car dealer a did.
if car dealer a sold 50 total cars, 30 would be blue.
if both dealers sold 70 total cars, car dealer b sold 14 more blue cars.

It would be the last answer because if you multiply the percentage 30% times 70 you get 21, and 50% gets you 35.

If both dealers sold 70 total cars, Car Dealer B sold 14 more blue cars.

any options?

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
