Final answer:
The total volume of cough syrup once mixed is 3.525 liters, calculated by adding 1,550 milliliters of syrup, 725 milliliters of cherry flavor, and 1.25 liters (or 1,250 milliliters) of water together.
Step-by-step explanation:
To calculate the total volume of cough syrup produced by a pharmacist, we need to add all the components' volumes together. The pharmacist mixes 1,550 milliliters of syrup, 725 milliliters of cherry flavor, and 1.25 liters of water. To find the total volume, first note that 1 liter is equivalent to 1,000 milliliters. Therefore, the 1.25 liters of water is equal to 1,250 milliliters. Now, we add up all the milliliters:
1,550 milliliters (syrup) + 725 milliliters (cherry flavor) + 1,250 milliliters (water) = 3,525 milliliters. To convert this to liters, we divide by 1,000:
3,525 milliliters ÷ 1,000 = 3.525 liters.
Therefore, the total volume of the cough syrup mixture is 3.525 liters.
