Answer:
Step-by-step 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.
