you buy a bottle of juice for $1.00. The juice costs 90 cents more than the empty bottle. How much does the empty bottle cost? The answer is not 10 cents.

PsyDAG,
With the information you have provided, I cannot see why the "answer is not 10 cents."
Sorry that I cannot help more. Thanks for asking.

Say the bottle costs x cents then cost of just the juice will be x + 90. Together the cost of the juice in a bottle is 2x + 90 = 100. Therefore the cost of the empty bottle is 5 cents.

PsyDAG,
If the cost of the juice is $.90, that is not part of x. I don't know how you get 2x for your formula. Your logic seems faulty. Can you explain?

the answer is 5 cents because if you look at a bottle, it says 5 cents .' its a tricky question
