A new technology makes inkjet printers more expensive to produce. At the same time, laser printers also become less expensive to buy. What would you expect to happen to the equilibrium price and quantity of ink jet printers in a perfectly competitive market?

Pearl’s Tattered Rags, the tent maker from our practice problems, has a production function of Q=4(KL)1/2 where K is production facilities and L is worker hours. What is the equation for her isoquant (putting K on the vertical axis) to produce 24 units in the long run?

Lucy makes a ham sandwich for lunch every day.  She insists on using exactly two slices of cheese and one slice of ham each day.  She has $20 per week to spend on these two things (assume all other sandwich items are free).  If cheese is $0.10 per slice and ham costs $0.20 per slice, how much of each will she consume each week?   Slices of Cheese = [cheese] Slices of Ham = [ham]

Graphically, the indifference curves for perfect substitutes are [drop1] and the indifference curves for perfect complements are [drop2]

For the demand curve P = 100-2Q, find the elasticity of demand at a price of 80.   Elasticity = 

If market demand is P = 100 – 0.6Q and supply is P = 20 + 0.4Q, solve for the market equilibrium.   Q = [quant] P = [price]

Groups of muscles are separated by thick connective tissue called:

Write T for true or F for false for the following statements. [1] 1. ATP causes the detachment of myosin from actin. [2] 2. T tubules conduct the action potential deep into the muscle. [3] 3. AChE attaches to the receptor to iniciate an action potential. [4] 4. Troponin is a regulatory protein. [5] 5. Sarcolemma stores and releases calcium into the muscle.

Of the various types of skeletal muscle fibers, the fibers that experience fatigue sooner are
