Question 178282: I have a word problem that I have worked two diffrent ways and I am still not able to come up with the answer.
THe problem is:
A store employee is counting $10.00 and $20.00 bills. If there are 6 times as many $10 bills as $20 bills and the total amount is $1760, find the number of each type of bill.
10x+60+20x=1760
30x+60=1760---then subtract 60 from both sides I get
30x=1700
x=56.6666666
I am not sure what I am doing wrong so any help with this would be greatly appreciated!!
Thanks in Advance.
