A vending machine has twice as many quarters in it as dollar bills. If the quarters and dollar bills have a combined value of $96.00 , how many quarters are in the machine?

Call N  = the  number of dollars  2N  the  number of  quaters.....so  we  have

 

,25(2N)  + 1N   =   96

 

1.50N  =  96

 

N  =  96  / 1,50   =  64   dollars

 

2(64)   =    128  quarters
