Tyrone empties his piggy bank and finds two $1 bills, a $5 bill, 13 quarters, 20 dimes, 8 nickels, and 35 pennies. How much money does Tyrone have? Think carefully first, then make a decision:
He has $2 in $1 bills because 2 times 1 equals 2. He has $5 in $5 bills because 1 times 5 equals 5. He has $3.25 in quarters because 13 times .25 equals 3.25. He has $2 in dimes because 20 times .1 equals 2. He has $.40 in nickels because 8 times .05 equals .4. He has $.35 in pennies because 35 times .01 equals .35. He has $13 because 2 plus 5 plus 3.25 plus 2 plus .4 plus .35 equals 13. So, the answer is 13.
