Question from Keisha, a parent:

Gross Receipts. Six thousand tickets are to be sold for a concert, some for $9 and the rest for $15each. If x is the number of $9 tickets sold , write an algebraic expression that represents the gross receipts from ticket sales, assuming all tickets are sold. Simplify the expression.


Since 6,000 tickets were sold, x of them for $9 each, how many were sold for $15 each? The x sold at $9 each earned receipts of x × $9. What was the revenue for the tickets sold at $15? What are the total receipts?
