Leila eats cake almost every week. Last week, she ate 6 cakes on Monday, 9 cakes on Friday, and on Saturday, she ate triple the number of cakes she ate on Monday. How many cakes does Leila eat? Let's answer step by step:
Combining Monday and Friday, Leila ate 6 + 9 = 15 cakes. On Saturday, she ate 6 * 3 = 18 cakes. Altogether, Leila ate 15 + 18 = 33 cakes. The answer: 33.
