To find the percentage increase in price from yesterday's price to today's price, we can use the following formula:
Percentage Increase = ((New Value - Old Value) / Old Value) x 100
Plugging in the given values, we get:
Percentage Increase = ((2.75 - 2.40) / 2.40) x 100
Percentage Increase = (0.35 / 2.40) x 100
Percentage Increase = 0.1458 x 100
Percentage Increase = 14.58%
Therefore, the percentage increase in price from yesterday's price to today's price is 14.58%, rounded to the nearest tenth of a percent.
