Profit is the difference between revenue and cost. It is given by:
Profit = Revenue - Cost
Given the profit function:
P(x) = 0.00019x³ - 2.6x + 1800
Where x is the number of customers.
For a profit of 40000:
40000 = 0.00019x³ - 2.6x + 1800
0.00019x³ - 2.6x - 38200 = 0
x = 593.6; x ≅ 594
594 customers need to be served so as to earn a profit of Php 40000
Given that:
N(t) = 7t⁴ - 4t³ + 150t + 17000
After 4 years, t = 4:
N(4) = 7(4)⁴ - 4(4)³ + 150(4) + 17000 = 19136
After 4 years the amount of citizens would be 19136.
