Price of Gold. The price of gold (end-of-year closing price in dollars per troy ounce) is shown in the table below. Year 1986 1996 2006 2016 Price $391 $369 $636 $1152 The prices shown in the table are not adjusted for inflation. Revise the above table to express all prices in terms of 2016 dollars. If you bought 3 ounces of gold in 1986 and sold it in 1996, would you have seen a profit (adjusted for inflation)? Explain. If you bought 3 ounces of gold in 2006 and sold it in 2016, would you have seen a profit (adjusted for inflation)? Explain.

A certain city's power company charges their residents for electricity usage on a daily basis. There is a basic charge of 11.57 cents. For each day the first 10 kWh cost 4.81 cents per kWh and any additional kWhs are 9.69 per kWh. (A kWh, or kilowatt-hour, is a unit of energy.) (a) Complete the following table using the information provided above. kWhkWh 0 5 10 15 20 cost (dollars)cost (dollars) kWhkWh 25 30 35 40 cost (dollars)cost (dollars) (b) We can define a piecewise function f(x)f(x) where xx is the kWh used in a day and f(x)f(x) is the cost, in dollars. This function would have the form f(x)={g(x)h(x)ififx∈Ax∈Bf(x)={g(x)ifx∈Ah(x)ifx∈B What functions g(x)g(x) and h(x)h(x) make up the piecewise function f(x)f(x)? g(x)=g(x)= for A = h(x)=h(x)= for B = Hint: A and B are intervals. If an interval uses ±∞±∞ write inf or -inf . (c) Using the above function, what is the cost of 26 kWh? dollars. (d) For 3 dollars, what is the maximum kWh usage for one…

The owner of a skating rink rents the rink for parties at $800 if 40 or fewer skaters attend, so that the cost per person is $20 if 40 attend. For each 5 skaters above 40, she reduces the price per skater by $0.50. (a) Construct a table that gives the revenue generated if 40, 50, and 60 skaters attend. No. of skaters Total Revenue 40 50 60 20 19 18 Price per Skater $800 $950 $ 1080 (b) Does the owner's revenue from the rental of the rink increase or decrease as the number of skaters increases from 40 to 60? lo The revenue increases. The revenue decreases. (c) Write the equation that describes the revenue for parties with x groups of five skaters more than 40 skaters. R(x) = (20-0.5x) (40+5x) (d) Find the number of skaters that will maximize the revenue. skaters (e) Find the maximum revenue. $ (f) When the revenue is at the maximum possible, what price is paid per skater? $
