A recipe for chocolate chip muffins states that it yields 12 muffins, with 320 calories per muffin. You instead decide to make mini-muffins, and the recipe yields 19 muffins. If you eat 5, how many calories will you consume?
The total calories for all the muffins is 12*320, or 3840. If you divide 3840 by 19, you get about 202 calories per muffin. So if you eat five you eat 202*5, or 1010.
