Answer 1

Shannon found a stack of 100 collectible fantasy horse cards in her desk that she had forgotten about. She randomly looked at 20 cards and got 8 centaur, 7 pegasus, and 5 unicorn cards.

Based on the data, estimate how many unicorn cards are in the stack.

Answer 2

To estimate how many unicorn cards are in the stack, we can use proportions.

If Shannon looked at 20 cards and got 5 unicorn cards, we can set up a proportion:

5/20 = x/100

Solving for x, we get:

x = 25

So, based on the data Shannon collected, we can estimate that there are around 25 unicorn cards in the stack.
