A company‘s cost, in dollars, of manufacturing x tablets, computers, can be presented by 20x+200. The companies predicted revenue of selling x tablet, computers, is 100 + 30x.
A) Write a polynomial expression that represents the profit of selling X tablets.
B) if the company sells 100 computers, how much profit will the company make?
Remember that
The profit is equal to the revenue minus the cost
so
Let
P -----> profit
P(x)=(100+30x)-(20x+200)
P(x)=10x-100
answer part a is (10x-100)
Part b
For x=100 computers
substitute the value of x in the expression of P(x)
p(x)=10(100)-100
p(x)=900
therefore
answer part b is $900
