My Bottle Deposit
In Delaware, you must pay a deposit on all bottles and you can return your bottles to receive your deposit back. If you buy a bottle of soda for $2 and the deposit is $1.60 less than the actual cost of the soda, how much is the deposit for?
Hint
The answer is not 40 cents.Answer
The answer is 20 cents. Since the deposit is $1.60 LESS than the cost of the soda, that the total for the cost for the soda must be $1.80, plus 20 cents deposit, which equals the $2 you paid for the soda.Hide Hint Show Hint Hide Answer Show Answer

EZ GOOD JOB

Easy if you are familiar with systems of equations... c+d=2 and c-1.60=d. Substitue for d and c+c-1.60=2... 2c-1.60=2... 2c=3.60... c=1.80. Substitue c and 1.80-1.60=d... .20=d
