Answer 1

9514 1404 393

Answer:

22 nickels

Explanation:

Let n represent the number of nickels in Joseph's piggy bank. Then the number of quarters is 62-n. The total value is ...

0.05n + 0.25(62 -n) = 11.10

-0.20n + 15.50 = 11.10 . . . simplify

4.40 = 0.20n . . . . . . . . . . add 0.20n-11.10

4.40/0.20 = n = 22

Joseph has 22 nickels in his piggy bank.
