First calculate the "weight" of each good -- that is the percentage of total expenditures spent on that good. In 2005, \$100 are spent on apples, \$100 on bananas, for a total of \$200. The weight of apples is 0.50 In 2006, price of apples went up by 100%, price of ...

The guy wants to consume 30,000 in t=1, but has y=60,000. So, he could in t0, borrow amount L. Since he will need to pay interest, at 6%, on the borrowed amount. So he wants L*(1+.06) = 30000. Solve for L. -- this being the additional consumption in t0.

The short-cut method is to use the Rule of 72. That is 72/rate = time needed for investment to double. So, 72/6.5 = 11.08 years Or you could do in more precisely by compounding an investment by 6.5% until it doubles.

Yes, you are on the right track. You have the equilibrium price, P=10. At P=10, average revenue must also be 10. Average cost is 10, so profits are zero.

With identical cost structures, the firms, in the long run, will all end up producing where the AC is minimized. So, P=10, plug this into the demand equation to get total Q. Take it from here
