A factory has a monthly operation cost of $280. The graph attached shows the total cost, C, for manufacturing x items in a month. What is the cost of manufacturing 21 items in one month?
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.
