An entrepreneur estimates his total profit (total revenue minus total cost) for his proposed company as p(x) = x3 − 4x2 + 5x − 20, where p is in hundreds of dollars and x is number of years the company has been in business. in which year (x) will the entrepreneur break even?
a.
year 1
b.
year 2
c.
year 3
d.
year 4

D

Step-by-step explanation:

Break even means the cost equals to the revenue, which means the profit is zero.

x*3-4x*2+5x-20=0

x*2(x-4)+5(x-4)=0

(x-4)(x*2+5)=0

x-4=0

x=4

it is true

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes
