"A bank teller has a total of 52 $20 bills in her cash drawer. The value of the bills is $900. If x represents the number of $10 bills, and y represents the number of $20 bills, determine the number of $10 bills that are in her drawer.

I am so confused by this question considering 52x20=1040 & the value in her drawer is only $900.
