1)The break-even point is the ticket price for which the event's income will equal expenses. Another way to think of the break even point is the ticket price when profit is $0. The equations given in an earlier problem were: P=((4000-25X)x)-7500

I=((4000-25x)x)

S=4000-25x

S=ticket price

x=tickets sold

a. Write and solve an equation that can be used to find the break-even ticket price for this particular planned concert.

b. Write and solve an inequality that can be used to find ticket prices for which the planned concert will make a positive profit.

c. Write and solve an inequality that can be used to find ticket prices for which the planned concert will lose money.

2)What similarities and differences do you see in tables, graphs, and rules of the function relating number of tickets sold, income, and profit to proposed ticket prices?
