Abottle contains 0.85 liters of orange squash concentrate. teresa adds 9 times as much water as the amount of orange squash in the bottle to make drinks for her birthday party.

Quantity of orange squash in the bottle =0.85 liters.

Quantity of water added= 9 times orange squash = 9*0.85 = 7.65 liters.

Now capacity of each cup is 250 ml

so let us convert the quantity of drink that is 7.65 liters into ml first.

Conversion : 1 liter =1000 ml

7.65 liters = 7.65 * 1000 = 7650 ml

If one cup can hold 250 ml of drink.

so for 7650 ml of drink number of cups will be 7650 divided by 250 = 30.6 or 30 cups.

So Teresa can make 30 cups of drink.
