Kadeem has a coin collection. He keeps 3 of the coins in his box, which is 10% of the collection.

Question

How many total coins are in his collection?

Answer 1

If Kadeem keeps 3 coins in his box, which is 10% of the collection, we can set up the equation:

0.10x = 3

Solving for x, we get:

x = 3 / 0.10
x = 30

Therefore, Kadeem has a total of 30 coins in his collection.
