Joseph has only nickels and quarters in his piggy bank. He has 62 coins total for a combined value of $11.10. How many nickels does Joseph have?

9514 1404 393

  22 nickels

Step-by-step 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.

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
