A concert promoter must sell 1000 tickets. She can sell premium tickets for $20 each, and discount tickets for $5 each. The total amount of money brought in from the sale of the tickets must be $14000. How many of each type of ticket must she sell? (a) Specify the variables you will use and what they represent. (i.e. give the "let ... be ..." statements) (b) Set up the equations that you would solve to answer the question above, but do not solve it.
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.
