Question 95730
a drive in cashier took $20 in bills to the bank to get change. she asked for twice as many dimes as nickels and three times as many quarters as nickels. Was the teller able to grant her request?
-------------
Let # of nickels be "x" ; value is 5x cents
# of dimes = "2x"; value is 10*2x = 20x cents
# of quarters = "3x"; value is 25*3x = 75x cents
----------------------
EQUATION:
value + value + value = 2000 cents
5x + 20x + 75x = 2000
105x = 2000
x = 2000/105 = 19.047...
--------------
x is not a whole number so the teller cannot satisfy the request.
