If 45% of people prefer tea, 35% prefer coffee, and 15% prefer both, what is the percentage of people who prefer only tea?

Step 1: Identify the percentage of people who prefer tea, which is 45%.
Step 2: Identify the percentage of people who prefer both tea and coffee, which is 15%.
Step 3: To find the percentage of people who prefer only tea, subtract the percentage of people who prefer both from the percentage of people who prefer tea.

Step 5: The result, 30%, is the percentage of people who prefer only tea.
