A group of students have begun 3d printing and selling mini statues of their classmates. They're trying to determine how much they'd need to charge for these 3d printed objects in order to justify purchasing their own 3d printer and materials.

The LulzBot TAZ Workhorse is currently listed for $3,989.99. The ABS filament currently costs $35.00 for a 1kg spool, but, you believe the price is falling by a consistent $0.007 per ounce each month. You expect this decline in price to continue at the same pace for at least the next six years.

The statues you've printed are averaging 3.25 ounces of material (including waste), and you plan to sell 22 statues per month. You've also realized there's a market for statues of your instructors. These instructor statues average 5.0 ounces of material (including waste), and sell for exactly twice the price of the student statues. You expect a robust market, and anticipate selling 31 of these each month as you expand across campus and to other universities.

You want to earn a return of at least 7.7% per quarter during the next four years. What do you need to charge for each statue to earn your desired rate of return

Please show your work and explain with the 5 button solution if possible. Thanks
