The profit function, P(x), revenue function, R(x), and cost function, C(x), are related by the equation P(x)=R(x)−C(x). Andrew has determined that the revenue and cost functions for a new product line at his business are given by these functions. R(x)=5x
C(x)=1200+3x
What is the profit function for Andrew’s new product line?

P(x)=2x−1200

P(x)=2x+1200

P(x)=8x−1200

P(x)=8x+1200

The answer is P(x)8x-1200

Step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
