(6) Erik receives an eight-year annuity-immediate with monthly payments. The first payment is $300 and payments increase by $6 each month. The payments are deposited in an account earning interest at a nominal rate of 6% convertible monthly. What is the balance in the account at the end of the eight years

Explanation:

You need to calculate the value of 8 × 12 = 96 different cash flows.

There is not a formula to calculate that, because the $6 dollar increase does not represent growing with a constant rate.

The monthly payments are:

Month            payment ($)

0 (today)             300

1                           306

2                          312

3                          318

n                          306 + 6 (n-1)

96 (last)               876

Then you must create a spreadsheet with these features:

Here a sample of the first three rows:

Month  Initial balance  Interest                    Deposit     Final balance

 0                  0                   0                          300          300

 1                 300             300×0.005 = 1.5    306          607.5

 2                607.5          607.5×0.005           312          922.54

When you do it up to the row 96, the final balance is the balance in the acccount at the end of the eight years.

The last row of your spreadsheet will show:

96           69,042.81      345.21                    876         70,264.03

Thus, the balance at the end of eight years will be $70,264.03

answer: in the short-run firms will respond by raising the price of turkey.

explanation: initially the long-run equilibrium is at a price of $5 per pound of turkey and a quantity of 50 million pounds per year. now, when webmd claims that a protein found in turkey will increase your expected lifespan by 4 years. the consumers demand for turkey will increase at every price shifting the demand curve to the right from d1 to d2. while, there will be no change in the supply curve in the short-run as it is not possible for producers to adjust supply so quickly. as a result the new equilibrium will occur at a higher price and a higher quantity of turkey.

thus, in the short run firms will respond by increasing the price of turkey, selling more quantity at a higher price and earning economic profits.
