Question

If she sold ice cream for $1.50 and sold water for $1.00 and made a total amount of $1,650. How much ice cream did she sell?

Answer 1

I think there is some information missing from your question. All that can be said about the solution is that she sold either 0 or an even number of ice creams, where the even number can be anything from 2 to 1100.

If she sold 0 ice creams, then she sold 1650 waters. If she sold 1100 ice creams then she sold 0 waters. If she sold 2 ice creams @ $1.50 each, then she sold 1650 - 3 = 1647 waters, because water is $1.00 per unit.
