Question

A recipe for blueberry muffins states that it yields 12 muffins, with 255 calories per muffin. You instead decide to make mini-muffins, and the recipe yields 20 mini-muffins. If you eat 5 mini-muffins, how many calories will you consume?

Answer 1

If the original recipe for blueberry muffins yields 12 regular-sized muffins, and each regular-sized muffin contains 255 calories, and you instead make mini-muffins, yielding 20 mini-muffins, you can calculate the number of calories per mini-muffin.

Calories per mini-muffin = Calories per regular muffin / Number of mini-muffins

Calories per mini-muffin = 255 calories / 12 mini-muffins

Now, you want to know how many calories you will consume if you eat 5 mini-muffins:

Calories consumed = Calories per mini-muffin * Number of mini-muffins eaten

Calories consumed = (255 calories / 12 mini-muffins) * 5 mini-muffins

Calories consumed = (21.25 calories/mini-muffin) * 5 mini-muffins

Calories consumed = 106.25 calories

So, if you eat 5 mini-muffins, you will consume 106.25 calories.
