How much mony will he make ?​

Answer 1

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 :-

`= 16 \: litres \: = 16000 \: ml`

`= (16000)/(200)`

`= 80 \: cups \: of \: coffee`

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 :-

`= (16000)/(80)`

`= 200 \: ml`

So , 200 ml of water is needed to make one cup coffee .

Quantity of water he needs to make 250 cups of coffee :-

`= 200 * 250`

`= 50000 \: ml`

So , Henri needs 50,000 ml of water to make 250 cups of coffee .

Number of water containers he will use :-

`= (50000)/(16000)`

`= 3.125 \\ = 3 \: water \: containers`

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 :-

`= 250 * 8`

`= 2000 \: cents`

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 .
