Problema Solution

A cashier has a total of 125 bills made up of fives and tens. The total value of the money is $815. How many ten-dollar bills does the cashier have?

Answer provided by our tutors

So x+y = 125

and 5x+10y=815

So solving both we get

x=87 and y=38.

So we have 87 $5 bills and $38 $10 bills
