Quantity of water with Henri = 16 litres
Quantify of water he will need for one cup of coffee = 200 ml
Number of cups of coffee he can make with a full cup of water :-
[tex] = 16 \: litres \: = 16000 \: ml[/tex]
[tex] = \frac{16000}{200} [/tex]
[tex] = 80 \: cups \: of \: coffee[/tex]
So , Henri can make 80 cups of coffee with one full bottle of water .
Quantity of water needed to make 80 cups of coffee = 16,000 ml
Quantity of water needed to make one cup of coffee :-
[tex] = \frac{16000}{80} [/tex]
[tex] = 200 \: ml[/tex]
So , 200 ml of water is needed to make one cup coffee .
Quantity of water he needs to make 250 cups of coffee :-
[tex] = 200 \times 250[/tex]
[tex] = 50000 \: ml[/tex]
So , Henri needs 50,000 ml of water to make 250 cups of coffee .
Number of water containers he will use :-
[tex] = \frac{50000}{16000} [/tex]
[tex] = 3.125 \\ = 3 \: water \: containers[/tex]
So , Henri will use 3 full water containers to make 250 cups of coffee .
Money charged per one coffee = 8 cents
Money charged for 250 coffees :-
[tex] = 250 \times 8[/tex]
[tex] = 2000 \: cents[/tex]
So , Henri will make 2000 cents if he sells 250 cups of coffee .
Therefore , Henri will use 3 full containers of water to make 250 cups of coffee and he he will make 2000 cents by selling 250 cups of coffee .
