Roger is conducting a biochemical experiment for the next 12
months. In the first month, the expenses are estimated to be
$10,000. As the experiment progresses, the expenses are expected
to increase by
2 percent each month. Roger plans to pay for the
experiment with a government
grant, which is received in four
monthly installments, starting a month after the experiment
completion date. Draw the cash flow diagram for this experiment.
Determine the amount of the monthly installment so that the
installments received are equal in value to the expenses incurred.
Annual nominal interest is 1
0 percent, compounded monthly.
