Problema Solution
In a jar there are twice as many nickels as dimes. There are three times as many quarters as nickels. If the jar has $1.70, how many are quarters.
Answer provided by our tutors
Let 'n', 'd', and 'q' stand for the number of nickels, dimes and quarters. We can write:
n=2d
q=3n
.05n+.25q+.10d=1.70
Using Algebrator to solve for 'n', 'd', and 'q', we get:
n=2
d=1
q=6
