Question 17154: I REALLY NEED HELP WITH SETTING UP THIS WORD PROBLEM!!! PLEASE HELP! I HAVE WORKED ON IT FOR HOURS AND JUST CAN'T GET TO WORK. THANKS!!

Andrew has $547 in ten-dollar, five-dollar, and one-dollar bills. There were 91 bills in all, and 10 more five-dollar bills than ten-dollar bills. How many one dollar bills does Andrew have?

Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
To solve this you need "quantity" information and "value" information.
Quantity Information is as follows:
Let "x" be the number of ten-dollar bills.
Then "x+10" is the number of five-dollar bills.
And 91-(x+x+10)= [91-2x-10]=[81-2x] one-dollar bills.
Value information:
Value of the ten-dollar bills is 10x
Value of the 5=dollar bills is 5(x+10)=5x+50
Value of the 1-dollar bills is 1[81-2x]
Equation:
Value of 10-dollar + Value of 5-dollar + Value of 1-dollar = 547 dollars
10x + 5x+50 + 81-2x = 547
13x +81 = 547
13x = 466
x = 35.85 (number of 10-dollar bills)
That doesn't make any sense. I suspect you did not post the information
stated in your problem regarding regarding how the number of one-dollar
bills relates to the number of ten-dollar bills. Check your problem
statement.
Cheers,
Stan H.
