Please help me! (Give me a reasonable answer)

Steven was at the car dealership with his parents. While he was waiting, he counted the number of each color car on the lot and constructed a bar chart to represent the data. If the car dealer started with 20 of each color, how many black cars has he sold? A) 5 B) 10 C) 15 D) 20

what is the model?

step-by-step explanation:

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
