Final answer:
To find the number of people who picked a vanilla cupcake, we need to calculate 50% of the total number of students who decided to take a cupcake.
Step-by-step explanation:
To find out how many people picked a vanilla cupcake, we need to calculate 50% of the total number of students who decided to take a cupcake.
- First, we multiply 72 (total number of students) by 50% (0.50 in decimal form) to find the number of students who picked a vanilla cupcake: 72 x 0.50 = 36.
- Therefore, 36 people picked a vanilla cupcake.
