Since there is two negative signs in the original equation, you need two negative signs in the equivalent one as well.

Because one of the negatives if before the fraction, it doesn't matter if the second negative is on the 13 or on the 12.

The answer is A.

Robin purchased a $160,000 182-day T-bill discounted to yield 1.96%. When he sold it 45 days later, yields had dropped to 1.82%.
Sav [38]

The amount earned by Robin is $224

  • Given the cost of 182-day T-bill = $160,000

If Robin is discounted to yield 1.96%, the amount yield is expressed as:

The yield of 1.96% = 1.96% of 160000

The yield of 1.96% = 0.0196 * 160000

The yield of 1.96% = $3136

Similarly, if the yield is dropped to 1.82%

The yield of 1.82% = 1.82% of 160000

The yield of 1.82% = 0.0182 * 160000

The yield of 1.82% = $2,912

Amount earned by Robin = $3136 - $2192

Amount earned by Robin  = $224

Hence the amount earned by Robin is $224
