Final answer:
Terry had 64 crayons in the box initially, as 16 crayons represent 25% of her box. This was calculated by dividing 16 by 0.25.
Step-by-step explanation:
To solve the problem of how many crayons Terry started with, knowing that giving away 16 crayons represents 25% of her box, we need to divide the number of crayons she gave away by the percentage this represents to find the total.
Given that 25% is equivalent to 0.25 in decimal form, we can set up the equation:
25% of the total crayons = 16 crayons given away,
- 0.25 × total crayons = 16,
- Total crayons = 16 ÷ 0.25,
- Total crayons = 64.
Therefore, Terry originally had 64 crayons in the box.
