Question 390418
She has at least one quarter, dime, nickel and penny;
She has a total of 11 coins;
She has 92 cents
The number of quarters plus the number of pennies equals the number of nickels;
The number of dimes plus the number of pennies equals the number of nickels. 
--------------------------
Equations:
p + n + d + q = 11
p+ 5n+10d+25q = 92
p - n+ 0d+  q = 0
p - n+  d+  0 = 0 
========================
These equations do not give whole number 
values for the variables.
