After Brett ate 25% of his jelly beans, he had 72 left. How many did he have originally?

• A. 90
• B. 94
• C. 95
• D. 96

Answer: (D)

To find the original number of jelly beans Brett had, we can use the information given about the percentage he consumed and the amount left. Brett ate 25% of his jelly beans, which means he has 75% remaining.

If 75% of the original amount is equal to 72 jelly beans, we can set up the equation:

0.75 * Original Amount = 72

To find the original amount, we can isolate it by dividing both sides of the equation by 0.75:

Original Amount = 72 / 0.75

Calculating this gives us:

Original Amount = 72 / 0.75 = 72 * (100/75) = 72 * (4/3) = 96

Thus, Brett originally had 96 jelly beans. This calculation aligns with the correct answer provided, confirming that the original number of jelly beans Brett had is indeed 96.
