A goldfish loses weight and gains weight depending on how much it is fed and how long in between. For every hour the fish isn't fed it loses 2 grams of weight. For every gram the fish is fed it gains twice that amount. If a goldfish weighs 40 grams to start, isn't fed for 3 hours, then is fed 5 grams of food, then isn't fed for 7 hours, how much does the goldfish weigh?
30 grams
