At a healthy foods store in Yardley, organic sugar used to retail for $4 per pound. The price was recently increased to $5 per pound. What is the percent of increase in the price of this item?

To calculate the percent increase in price, we first find the difference between the new price and the old price, and then divide that difference by the old price.

Old price: $4 per pound
New price: $5 per pound

Difference in price = New price - Old price
= $5 - $4
= $1

Percent increase = (Difference in price / Old price) * 100%
= ($1 / $4) * 100%
= 0.25 * 100%
= 25%

Therefore, the percent increase in the price of organic sugar is 25%.
