Wheres The DollarAlgebra Level pending
You see a shirt for 97 dollars. You don't have the cash so you borrow 50 bucks from your mom and 50 bucks from your dad, 50+50=100. So you buy the shirt and you have 3 dollars change. You give your dad 1 dollar and your mom 1 dollar, and you keep 1 dollar. Now you owe your mom 49 dollars and your dad 49 dollars. 49+49=98 + your 1 dollar=99 dollars. Where is the missing 1 dollar?
