Answer:
Price = $4.50
Maximum revenue = $2,430
Step-by-step explanation:
The concession stand sells 600 bags of peanut at $4.00 (600, $4.00).
If there is a $1 increase in price, the number of bags old will decrease by 120, which mens that 480 bags of peanuts will be sold at $5.00 (480, $5.00).
Tracing a linear relationship between price and quantity sold with the two given points:


The revenue function is given by the price multiplied by the quantity sold:

The value of 'Q' for which the derivate of the revenue function is zero, is the output level for which revenue is maximum:

The total revenue of 540 units at $4.50 per unit is:

Cookie sales: 12 weeks divided by 2 weeks = 6 weeks x $360 = $2,160
Car wash: 12 weeks divided by 3 weeks = 4 weeks x $450 = $1,800
Recycling: 12 weeks divided by 4 weeks = 3 weeks x $600 = $1,800
Yard work: 12 weeks divided by 2/5 weeks = 30 x $80 = $2,400
