Question

Draw 10 coins to show an amount between 50cent and $1.00

Answer 1

Six 10-cents-coins

Four 5-cent-coins.

Explanation:

First, we select a specific amount, 80 cent is between 50 cent and $1.00.

So, we can have this 80 cent separate it into six 10-cents-coins, which in total is 60 cents. Then, the 20 cents missing we could have it in four 5-cents-coins. At the end we will have 6+4= 10 coins in total.
