Question

Nicole has an action figure collection. She keeps 210 of the action figures on her wall, which is 70% of her entire collection. What is the total number of action figures in Nicole's collection?

a) 150
b) 210
c) 300
d) 420

Answer 1

The correct answer is option c) 300. By solving the proportion 0.70 × (total collection) = 210, we determine that Nicole's complete collection consists of 300 action figures.

Step-by-step explanation:

The correct answer is option c) 300. To find the total number of action figures in Nicole's collection, we use the information that 210 action figures represent 70% of her entire collection. We can set up a proportion in which 70% corresponds to 210 action figures:

70% (or 0.70) of the total collection = 210 action figures

Thus, 0.70 × (total collection) = 210

To find the total collection, we divide 210 by 0.70:

(total collection) = 210 ÷ 0.70 = 300 action figures

Therefore, Nicole's entire action figure collection consists of 300 action figures.
