Solution

To solve this problem, we need to add the number of people who like tea and the number of people who like coffee. Then, we subtract the number of people who like both to avoid double-counting.

So, the calculation is as follows:

80 (tea lovers) + 60 (coffee lovers) - 30 (lovers of both) = 110 people

Therefore, 110 people like at least one item.
