Final answer:
To calculate the percent of increase, subtract the original price from the new price, divide by the original price, then multiply by 100. The Student Government's price increase from $10 to $25 is a 150% increase.
Step-by-step explanation:
To calculate the percent of increase in price when the Student Government buys sweatshirts for $10 and sells them for $25, we follow these steps:
- Find the difference in price by subtracting the original price ($10) from the new price ($25).
Difference = $25 - $10 = $15. - Divide the difference by the original price to find the increase in terms of the original price.
Increase = $15 / $10 = 1.5. - Multiply the resulting number by 100 to convert it into a percentage.
Percent of increase = 1.5 × 100% = 150%.
Therefore, the percent of increase is 150%.
