nickels, n?
0.05n + 0.25(36 – n) = 6
0.05n + 0.25(36 – n) = 36
n + 0.05 = 0.05n
n + (36 – n) = 36

Answer:

Let n be the number of nickels and q be the number of quarters, then

n + q = 36 . . . (1)

0.05n + 0.25q = 6 . . . (2)

From (1): q = 36 - n . . . (3)

Putting (3) into (2) gives:

0.05n + 0.25(36 - n) = 6
