Problema Solution
Amy has 100 coins work $12.50, all nickels, dimes, and quarters. she has 25 fewer quarters than dimes. how many of each type does she have?
Answer provided by our tutors
Let 'n', 'd', and 'q' stand for the number of nickels, dimes, and quarters. We can write:
n+d+q=100
.05n+.10d+.25q=12.50
q=d-25
using Algebrator to solve for n, d, and q, we get:
n=25
d=50
q=25
