Question

The revenue from selling x bracelets is r(x)=8x

the cost of buying x bracelets is c(x) 3x+12 the profit from selling x bracelets is p(x) = r(x) - c(x)
Write a function for p(x), the profit from selling x bracelets

A) p(x)=11x+12

B) p(x)=5x+12

C) p(x)=11x-12

D) p(x)=5x-12

Answer 1

Answer: Seeing that you have to subtract c and r you subtract the 3x from the 8x and also subtract 12 from 0 and you get P(x)=11x--12

Explanation:

Answer 2

Correct option is:

D) p(x)=5x-12

Explanation:

r(x)=8x

c(x)= 3x+12

p(x) = r(x) - c(x)

⇒ p(x)=8x-(3x+12)

⇒ p(x)=8x-3x-12

⇒ p(x)=5x-12

Hence, Correct option is:

D) p(x)=5x-12
