A survey shows that 60% of people prefer tea over coffee. If 240 people were surveyed, how many prefer coffee? (2023)
  • Step 1: Understand that 60% of the surveyed people prefer tea.
  • Step 2: Calculate how many people prefer tea by finding 60% of 240.
  • Step 3: To find 60% of 240, multiply 240 by 0.60 (which is the decimal form of 60%).
  • Step 4: Perform the multiplication: 240 * 0.60 = 144. This means 144 people prefer tea.
  • Step 5: To find out how many people prefer coffee, subtract the number of people who prefer tea from the total number of surveyed people.
  • Step 6: Calculate the number of people who prefer coffee: 240 - 144 = 96.
