Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
For a certain company, the cost for producing x items is 55z+300 and the revenue for selling x items is 95z-0.5x^2.
part a: set up an expression for the profit from producing selling x items. we assume that the company sells all of the items that it produces.
profit = -0.5x^2 + 40x - 300
part b: Find the values of x that will create a profit of 50
the values are (10, 70)
part c- Is it possible for the company to make a profit of $2,500?
I need help with part C, I think I got the first two parts correct!
