Answer the following question.
Kira is making breakfast for herself. She fries 3 sausages then scrambles 6 eggs and cooks each item of food separately. If it takes 5 minutes to fry each sausage and 4 minutes to scramble each egg then how long, in minutes, did it take for Kira to make her breakfast?

The answer is 39.
