You can put this solution on YOUR website! Jim has a total of 50 coins. Some are nickels and some are dimes. altogether he has $4.15. How many dimes does he have? How many nickels?***********
Than is states that I have to cheack it!
----------
Let the # of nickels be "x" ; value of these is 5x cents
# of dimes is "50-x" ; value of these is 10(50-x) = 500-10x cents
--------------
EQUATION:
value + value = 415 cents
5x + 500-10x = 415
-5x = -85
x = 17 (# of nickels: worth 5*17 = 85 cents)
50-x = 33 (# of dimes; worth 10*33 = 330 cents)
---------------
Checking:
85 cents + 330 cents = $4.15
