Question 705999
Neil has a total of twelve $5 and $10 bills in his wallet.He has 5 times as many $10 bills as $5 dollar bills. How many of each does he have?
.
Let x = number of $5 bills
then from "Neil has a total of twelve" we have
12-x = number of $10 bills
.
From: "He has 5 times as many $10 bills as $5 dollar bills." we get our equation:
x = (1/5)(12-x)
multiplying both sides by 5:
5x = 12-x
6x = 12
x = 2 (number of $5 bills)
.
Number of $10 bills:
12-x = 12-2 = 10
