Are the calculations by the student below correct?  IF not, what went wrong?  Explain using mathematical terms/words and correct the error if necessary. Sales A concert promoter wants to book a rock group for a stadium concert. A ticket for admission to the stadium playing field will cost $125, and a ticket for a seat in the stands will cost $175. The group wants to be guaranteed total ticket sales of at least $700,000. How many tickets of each type must be sold to satisfy the group's guarantee? Define variables, set up a mathematical model as a system of linear inequalities, and draw its graph.  Answer: Define Variables:  x = seat in stands and y = seat in playing field; the inequality 125x + 175y ≥ 700,000 models this question and the graph of the solution is below.
