Cost and revenue

Problem:



Solution:

Part a) f(x) = 10000 + 550x

This is because his total cost is the sum of the startup cost and the per computer cost

Part b) g(x) = 1199.99x

This is because he revenue is simply the revenue of selling the computers

Part c) g(14) - g(11)

This is the change in revenue.

Part d) f(c + d) - f(d)

This is the change in cost.

Part e) h(x)  = g(x) - f(x)

Profit is revenue minus cost

Part f) h(x) = 1199.99x - (10000 + 550x) = 649.99x - 10000

Part g) 16,

This is the minimal integer x that make h(x) > 0
