To calculate the maturity of this note,
we use a simple formula first to get the interest which is:
I = Principal (amount owed) X Interest Rate (%) X Time (length of loan)
The days is only divided by only 360 days instead of 365 days. This is because commercial loans often use 360-day calendar years instead of 365-day calendar years. But not all banks used this as their calendar year,
I = Prt
= ($80000) (0.05) (120/360)
= ($80000) (0.01666666666)
I = $ 1,333.33
To get the maturity value, the formula is: M = Interest + Principal
M = I + P
= $1,333.33 + $80,000
= $81,333.33 or $81,333, letter C
