A clothing business finds there is a linear relationship between the number of shirts, n it can sell and the price, P, it can charge per shirt. In particular, historical data shows that 3thousand shirts can be sold at a price of $78 each and that 7thousand shirts can be sold at a price of $62 each. Write an equation of the form P(n)=mn+b that gives the price P they can charge for n thousand shirts
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.
