First: how many liters of milk do we have?
96 provided by Mirri plus the milk that the other cat has brought.
Since the other cant has enough milk to last.
Thus, the total amount is
[tex]96[/tex]Second: How many lt do we need every day?
Since every cat needs 4 lt and there are 8 cats, then we need
[tex]4\times8[/tex]litters per day.
Third: The other cat brought enoug milk to last 2 more days, so we have to add 2 days to the numbers we have obtained.
Four: If we combine the last three parts
[tex]\frac{96}{4\times8}+2=d.[/tex]
