Suppose that Lilly spends all of her income on baby spinach and broccoli (she has just learned that it is the perfect diet for her brain). She can just afford 11 packs of baby spinach and 4 broccolis per week. She could also use her entire income to purchase 3 packs of baby spinach and 8 broccolis per week. The price of one pack of baby spinach is CZK 30. What price does Lilly pay for one broccoli? Please, insert numerical value only.
