Hundred dollar bills is 100 dollars so if you have four of them you get 400
ten dollar bills is 10 dollars so if you have 23 of them you have 230
one dollar bills is 1 dollar so if you have 17 of them you 17 dollars
400+230+17= 647
One dime is equal to 10 cents so if you have 46 of them you have $4.60
One penny equals 1 cent so 19 pennies equal 19 cents
$4.60+.19= $4.79
$647+$4.79= $651.79<---- that's your answer
