Question

In a cash drawer, there is $125 in $5 and $10 bills. The number of $10 bills is twice the number of $5 bills. How many of each type of bill is in the drawer?

Answer 1

Explanation:

You can use the equations:

x = 2y

where x is the number of $10 bills and y the number of $5 bills and:

10x+5y = 125

Solving gives x=10 and y = 5, or in other words there are 10 $10 bills and 5 $5 bills
