Final answer:
To find the total volume of the cough syrup mixture, convert the milliliters to liters and then sum the volumes of syrup, cherry flavor, and water. The total volume after mixing is 3.525 liters.
Step-by-step explanation:
To calculate the total volume of the cough syrup mixture, we need to add all the individual volumes of the components together. The pharmacist mixes 1,550 milliliters of syrup, 725 milliliters of cherry flavor, and 1.25 liters of water. Remember that 1 liter is equivalent to 1,000 milliliters. Thus, we can convert the milliliters to liters before adding them together.
First, convert milliliters to liters by dividing by 1,000:
- Syrup: 1,550 milliliters / 1,000 = 1.55 liters
- Cherry flavor: 725 milliliters / 1,000 = 0.725 liters
Now add the volumes together:
1.55 liters (syrup) + 0.725 liters (cherry flavor) + 1.25 liters (water) = 3.525 liters.
Therefore, once mixed, the total volume of the cough syrup is 3.525 liters.
