Final answer:
The price of the vaccine vial increased by approximately 958.82% from the original price of $85 to $900.
Step-by-step explanation:
To calculate the percent increase in the price of a vaccine vial, you must follow these steps:
- Find the difference in price between the original and final amounts. In this case, it's $900 - $85 = $815.
- Divide the price difference by the original amount to find the increase relative to the original price. So, you get $815 / $85 = 9.5882.
- To find the percent, you multiply the decimal by 100. Thus, 9.5882 * 100 = 958.82%.
Therefore, the vial increased by approximately 958.82%.
