When Forrest sells a tree for $20, he can sell 25 trees a day. For every$1.50 he lowers the price. he sells 7 more trees each day. At what value should he fix the price per tree to maximize his daily revenue? How many trees should he expect to sell at this price?

Quincy purchased a used car for $1000. He decided to sell the car for 10% above his purchase price. Quincy could not sell the car so he reduced his asking price by 10%. If he sells the car at the reduced price, will he have a profit or a loss or will he break even? Explain how you arrived at your answer.

Motor neurons in mammals transmit signals from the brain to skeletal in ms $\left( 10 ^ { - 3 } \mathrm { s } \right)$ it will take for a signal to get from your brain to your hand.

Suppose an analog audio signal is sampled 16,000 times per second, and each sample is quantized into one of 1024 levels. What would be the resulting bit rate of the PCM digital audio signal?

When the owner of a gas station sets the price of 1 gallon of unleaded gasoline at $4.10, he can sell approximately 1500 gallons per day. When he sets the price at$4.25 per gallon, he can sell approximately 1250 gallons per day. Let G(x) denote the number of gallons of unleaded gasoline sold per day when the price is x dollars. Assume that G(x) is a linear function of x. Approximately how many gallons will be sold per day if the price is set at $4.35 per gallon?
