Answer:
$ 44262,74
Step-by-step explanation:
The interest Paid was about october, november an december 2018 (3 months).
Interest rate is 12% anual, but to convert to monthly is necessary to apply compound interest formula:
MonthlyRate = ((1 + Anual Rate) ^1/12 − 1)
Monthly Rate= ((1 + 0,12)^(1/12) - 1) = 0,9488%
3 months= 3 * 0,9488% = 2,8466%
1260 is equivalent to 2,8466%, so 100% is equal to original debt :
1260 * 100% / 2,8466% = $44262,74
