Tucker Boats purchased boat moving equipment, office furniture, and boat repair machinery. Tucker Boats paid $6,880 in cash and signed a four-year, 9.6%, $20,000 installment note payable to First National Bank. Equal monthly principal and interest payments of $503.42 are due the 6th of each month, beginning October 6. (The note assumes a 360-day year and 30 days of interest charged for each full month. Months with 31 days accrue only 30 days of interest, but so does September. The date the loan is signed bears interest. Interest is accrued to the nearest penny.)
