John and Sally Claussen are considering the purchase of a
hardware store from John Duggan. The Claussens anticipate that the
store will generate cash flows of $73,000 per year for 20 years. At
the end of 20 years, they intend to sell the store for an estimated
$430,000. The Claussens will finance the investment with a variable
rate mortgage. Interest rates will increase twice during the
20-year life of the mortgage. Accordingly, the Claussens’ desired
rate of return on this investment varies as follows: (FV of $1, PV
of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1)
(Use appropriate factor(s) from the tables
provided.)
| Years 1–5 | 7 | % | |
| Years 6–10 | 9 | % | |
| Years 11–20 | 11 | % | |
Required:
What is the maximum amount the Claussens should pay John Duggan for
the hardware store? (Assume that all cash flows occur at the end of
the year.) (Do not round intermediate calculations. Round
your final answers to nearest whole dollar amount.)







| Year | PV of $73,000 cash flow | PV of $430,000 selling price | Maximum paid for store |
| 1-5 | $299,315 | $299,315 | |
| 6-10 | $184,545 | $184,545 | |
| 11-20 | $151,407 | $151,407 | |
| 20 | $89,870 | $89,870 | |
| Total | $635,267 | $89,870 | $725,137 |
Maximum amount that should be paid for the store is $725,137.

Assign the NMR peaks below DIRECTLY onto the paper,
please!!!!
The impurities are water at 2.19 ppm and acetone at 1.6 ppm. So
just ignore those peaks. The peaks for the aromatic Hydrogens can
be grouped up to one (I believe they are the left most peaks at
around 7 to 7.5 ppm. Given that please assign the rest of the
hydrogens.
