R(x) = 150 (x2 + 1) gives the monthly revenue in millions x months after an ad campaign. in how many months will the revenue be 30 million? a) 2 months b) 4 months c) 6 months d) 8 months

A) 2 months

Step-by-step explanation:

Given the revenue as a function of the time in months, to make 30 million in revenue, the function will be equated to the amount and then solved for x which is the number of months.

As such, if the revenue function is

R(x) = 150/(x2 + 1)

Then

R(x) = 150/(x2 + 1)  = 30

(x2 + 1) = 150/30

x2 + 1 = 5

x2 = 4

x = √4

x = 2

it will take 2 months to generate 30 million

50x5=$250
