Concepts
Step 1: Understand that 70% means 70 out of every 100 people.
Step 2: We need to find out how many people prefer tea out of 50 surveyed.
Step 3: Convert 70% to a decimal. 70% as a decimal is 0.7.
Step 4: Multiply the total number of people surveyed (50) by the decimal (0.7).
Step 5: Calculate 0.7 * 50, which equals 35.
Step 6: Conclude that 35 people prefer tea.
