Question 842060
q = how many quarters
n = how many nickels
d = how many dimes
-
1 quarter = 0.25 dollar
1 nickel = 0.05 dollar
1 dime = 0.10 dollar



FORMING EQUATIONS

Thirty-four coints in bank, {{{q+n+d=34}}};
Four quarters, {{{q=4}}};
Twice as many nickels as quarters, {{{n/q=2}}};


Those equations are now enough for solving for n and d.
The value of q is already given, so you will quickly obtain TWO equations in TWO unknowns.

Notice that the coin conversion factors will not be needed.
