n = number of nickels
d = number of dimes
q = number of quarters
To find how much money he has, find , , and

In this case,
n = number of nickels
d = number of dimes
q = number of quarters
as before, but what is known is how much money he has
and not the total number of coins
(in cents)
Solve the 1st equation for n
Now find d and n in in terms of q
The answer is 19 quarters, 114 dimes, and 30 nickels
You can check answer by plugging values for d, n, and q into
the original equation
