You can put this solution on YOUR website! I'm sure there are a lot of ways to solve this, but I would do it by using up the smallest denominations first. Is there a limit of how many of each you need to use? Else, let's go with the smallest amounts of the smallest monies.
.
5 pennies (you can't use less than 5 or you won't be able to get to $70.00 exactly)
2 nickels (you're going to want the pennies, nickels, and dimes to be able to be added to the quarters)
1 dime
So far, you have .25
Add three quarters to make $1.00. You'll need 69 more. Want to guess how many ones?
4 1-dollar bills. Now you have $5.
Add 1 5-dollar bill to make it $10.
Now add 6 10-dollar bills to get $70.
.
Are you sure that's the whole problem? There are many solutions for the problem as written. Usually, these types of problems specify a maximum of each type.
