A clothing business finds there is a linear relationship between the number of shirts, nn, it can sell and the price, pp, it can charge per shirt. In particular, historical data shows that 30003000 shirts can be sold at a price of $9$9, while 40004000 shirts can be sold at a price of $5$5. Give a linear equation in the form p=mn+bp=mn+b that gives the price pp they can charge for nn shirts. P=_____
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.
