Final answer:
A four-bottle carton contains 4000 milliliters. The amount in part (a) equals 4 liters. The cost per liter is $0.5625.
Step-by-step explanation:
a) To find out how many milliliters are contained in a four-bottle carton, we need to know the capacity of each bottle. Let's assume each bottle has a capacity of 1 liter (1000 milliliters).
Therefore, the total milliliters in a four-bottle carton is 4 liters multiplied by 1000 milliliters, which equals 4000 milliliters.
b) To convert the amount in part (a) to liters, we divide 4000 milliliters by 1000, which equals 4 liters.
c) To find the cost per liter, we divide the total cost of the carton ($2.25) by the volume in liters (4 liters).
Therefore, the cost per liter is $2.25 divided by 4, which equals $0.5625 per liter.
