Simon has 20 quarters and 12 dimes. He wants to purchase ice cream for his friends. An ice cream cone costs $1.00. How many cones can SImon buy for his friends?

6 ice cream cones

Step-by-step explanation:

Convert 20 quarters and 12 dimes into dollar amounts.

Quarters: 20 * 0.25 = 5.00

Dimes: 12 * 0.10 = 1.20

Now, add up the total amount in coins.

5.00 + 1.20 = $6.20

If ice cream cones cost a $1.00 each, then Simon can buy 6 ice cream cones for $6.00. He will have $0.20 left.
