Answer:

Step-by-step explanation:

After defining variables as ...

q = number of quarters

n = number of nickels

we can write two equations. One of them expresses the total number of coins:

q + n = 30

The other expresses the total value of the coins:

0.25q + 0.05n = 3.70

_____

The solution to these equations is (n, q) = (19, 11).
