Final answer:
To find the percentage increase, convert both volumes to milliliters, find the volume increase, and then divide this by the original volume, which gives a result of a 150% increase.
Step-by-step explanation:
To calculate the percentage increase in volume of juice from 500 ml to 1.25 liters, first convert both volumes to the same unit. Recall that 1 liter equals 1,000 milliliters. Therefore, 1.25 liters is equivalent to 1.25 × 1,000 = 1,250 milliliters. We then use the formula for percentage increase:
Percentage Increase = ((New Volume - Original Volume) / Original Volume) × 100%
Substitute the given volumes into the formula:
Percentage Increase = ((1,250 ml - 500 ml) / 500 ml) × 100%
The increase in volume is 1,250 ml - 500 ml = 750 milliliters. Now divide this increase by the original volume:
Percentage Increase = (750 ml / 500 ml) × 100%
Percentage Increase = 1.5 × 100%
Percentage Increase = 150%
The volume of juice has increased by 150%.
