Ross Recreations Company, LLC operates a summer camp in Montreal, Quebec. The following cost data for a 12-
week summer camp is as below:
Charge per camper =$400/week
Variable cost per camper =$220/week
Fixed costs =$240,000 per summer season
Capacity per week =200 campers
Determine the following:
a. the total number of campers to breakeven for the season
b. the profit if the camp is operated at 90% capacity
c. the additional profit that can be made if a discount of $100 per week is given for another 10 campers

Kal Tech Engineering Inc. manufactures video games for ‘The Play Station’. Variable costs are estimated to be $20
per unit and fixed costs are $10,875. The demand to price relationship for this product is Q = 1,000 - (4 × P) where
P is the unit sales price of the game and Q is the demand in number of units.
a. Find the breakeven quantity (or quantities).
b. What is the company's maximum possible revenue?
c. What profit would the company obtain by maximizing its total revenue?
d. What is the company's maximum possible profit?

One hundred compressors of 200 H.P. rating are being considered for purchase by the state highway department.
The compressor index was 400 five years ago, and is 520 today. The cost of 150 H.P. compressors bought five years
ago is as follows. For the first 50 compressors, the cost was $2,000 per unit and for the second 50, the cost was $
2,400 per unit.
Find the cost of 100 compressors of 200 H.P rating today.

Write a program that uses FSOLVE() to solve for the volumetric flow rate (m3/s) in each segment of the pipe flow network given below. Use the following properties for water: density = 1000 kg/m3, viscosity = 0.00089 N s/m2 and pipe roughness = 0.00025 m.

The following differential equations describe the behavior of a hydraulic valve system

The noise output of a resistor is amplified by a noiseless amplifying having a gain of 60 and a bandwidth of 20 KHz. A meter connected at the output of the amplifier reads 1mV RMS. if the bandwidth of the amplifier is reduced to 5 KHz, its gain remaining constant, what does the meter read now?

Plot the frequency response for a PLL with an open loop gain of 20 KHz/rad. On the same log paper, plot the response with a single-pole loop filter with a cutoff frequency of 100 rad/s and a two-pole filter with the same cutoff frequency.

1. Determine the change in frequency for a VCO with a transfer function of 0.5 V/rad and phase error of 0.75 rad

2. Plot the frequency response for a PLL with an open loop gain of 20 KHz/rad. On the same log paper, plot the response with a single-pole loop filter with a cutoff frequency of 100 rad/s and a two-pole filter with the same cutoff frequency.
