Final answer:
To find the percent increase of the price, calculate the difference between the selling price and the purchase price, then divide by the purchase price and multiply by 100.
Step-by-step explanation:
To find the percent increase of the price, we need to calculate the difference between the selling price and the purchase price, and then divide that difference by the purchase price. Finally, we multiply the result by 100 to get the percentage.
The difference in price is $375 - $150 = $225.
The percent increase is ($225 / $150) * 100 = 150%.
Therefore, the percent increase of the price is 150%.
