r(b) = 12b
c(b) = 4 + 3.3b
I think profit is revenue minus the cost, so p(b) = r(b) - c(b)
= 12b - (4 + 3.3b)
12b - 4 - 3.3b //Combine like terms
8.7b - 4
Answer: D
//Hope it helps and it's right.
Answer:
Y = 2x + 4
Step-by-step explanation:
As the question said the slope is 2, so you put 2 with x.
The point you are given is (1,6), so you backtrack to X = 0, and since the slope is 2 you subtract 2 from 6. now you're at (0,4), giving you 4.
