The revenue from selling x necklaces is f(x) = 10x. The cost of buying x necklaces is c(x) = 4x + 15.
The profit from selling x necklaces is p(x) = f(x) – cx).
Write a function for p(x), the profit from selling x necklaces.
A. p(x) = 6x + 15
B. p(x) = 6x - 15
C. p(x) = 14x + 15
D. p(x) = 14x - 15

huh? im pretty sure it is in 199

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
