Calculating the old and New currency.
Anticipating a great deal of vexation and difficulty in the calculations of sums due in the old currency by those who are not "good in figures," and having observed a number of persons already (who are not deficient in that respect,) fall into an error which looks very plausible at the first glance, I thought proper to address you and submit to the public a very simple solution of the difficulty, viz: Multiply the sum due by 3 and divided by 2; the result will be the amount due in notes of any denomination above $5, and if change is required to be given of a less sum than $10, multiply the sum due by 2 and divide by 3; the result will be the amount required to be given in change. For example: A owes B $8.75; $8.75 multiplied by 3 and divided by 2 makes $13.12½. A gives B a $20 note in payment; $13.12½ from $20 leaves $6.87½ multiplied by 2 and divided by 3 and $4.58½ is the result, which B gives in change. Or thus; $20 is worth $13.33½ subtract $8.75, leaves $4.58½, as before. The error mentioned above, which many fall into, is adding one-third to the amount due when payment is made in the old issue.
