Start by using `x` to represent the total amout of bills. From there, we can say that `5x` represents the five dollar bills and `10x` represents the ten dollar bills. But, they tell us there are twice as many five's as ten's. Therefore, `2 * 5x` more accurately represents the amount of fives. Finally, there is `560` dollars.
