70×5+80×5=750
70×5=350
80×5=400
70×6+80×6=900
70×6=420
80×6=480

Answer 2

Calculation of Milk Consumption

To calculate the total amount of milk consumed over the two weeks, we need to determine the daily milk consumption for each week and then multiply it by the number of days the cafeteria operated.

In the first week, the cafeteria consumed 70 liters of milk per day for 5 days. Therefore, the total milk consumption for the first week is:

First Week Milk Consumption = 70 liters/day * 5 days = 350 liters.

In the second week, the cafeteria consumed 80 liters of milk per day for 5 days. Therefore, the total milk consumption for the second week is:

Second Week Milk Consumption = 80 liters/day * 5 days = 400 liters.

To find the total milk consumption over the two weeks, we add the milk consumption for each week:

Total Milk Consumption = First Week Milk Consumption + Second Week Milk Consumption = 350 liters + 400 liters = 750 liters.

Therefore, the cafeteria consumed a total of 750 liters of milk over the two weeks if it operated for 5 days each week.

If the cafeteria operated for 6 days each week, we can calculate the total milk consumption for the two weeks using the same method.

In the first week, the cafeteria consumed 70 liters of milk per day for 6 days. Therefore, the total milk consumption for the first week is:

First Week Milk Consumption = 70 liters/day * 6 days = 420 liters.

In the second week, the cafeteria consumed 80 liters of milk per day for 6 days. Therefore, the total milk consumption for the second week is:

Second Week Milk Consumption = 80 liters/day * 6 days = 480 liters.

To find the total milk consumption over the two weeks, we add the milk consumption for each week:

Total Milk Consumption = First Week Milk Consumption + Second Week Milk Consumption = 420 liters + 480 liters = 900 liters.

Therefore, if the cafeteria operated for 6 days each week, it consumed a total of 900 liters of milk over the two weeks.

Please note that the calculations above are based on the given information and assumptions about the cafeteria's milk consumption.
