Answer

The original price of the machine was approximately \$324,230.77.

Solution

1. Let the original price be \( x \). 2. A discount of \( 13 \frac{1}{3}\% \) is equivalent to a discount of \[ 13 \frac{1}{3}\% = 13.333\ldots\% = \frac{2}{15}. \] 3. This means that after the discount, the price paid is \[ x - \frac{2}{15}x = \frac{13}{15}x. \] 4. We are given the discounted price as \( \$281,\!000 \), so: \[ \frac{13}{15}x = 281,\!000. \] 5. Solve for \( x \) by multiplying both sides by \( \frac{15}{13} \): \[ x = 281,\!000 \times \frac{15}{13}. \] 6. Calculate the product: \[ 281,\!000 \times 15 = 4,\!215,\!000, \] so \[ x = \frac{4,\!215,\!000}{13} \approx 324,\!230.77. \] 7. Therefore, the original price of the machine was approximately \( \$324,\!230.77 \).

To find the original price of the machine, we can set up the relationship based on the discount given. If the discount is \( 13 \frac{1}{3} \% \) (which is \( \frac{1}{3} \) or approximately \( 0.3333 \)), then the company paid \( 100\% - 13 \frac{1}{3} \% = 86 \frac{2}{3} \% \) (or \( 0.8667 \)) of the original price. Let the original price be \( x \). Thus, we have: \[ 0.8667x = 281,000 \] Now, solving for \( x \): \[ x = \frac{281,000}{0.8667} \approx 323,885.62 \] The original price of the machine rounds to approximately \( \$323,885.62 \). Keep in mind that remembering the actual percentage is crucial. Mistakes can happen when working with fractions if one is not careful!
