Answer:

  • 16 quarters
  • 9 nickels

Step-by-step explanation:

Let q represent the number of quarters. Then the value of the coins, in cents, is ...

  5(25 -q) +25q = 445

  125 +20q = 445 . . . . . . . simplify

  20q = 320 . . . . . . . . . . subtract 125

  q = 16 . . . . . number of quarters

  25 -q = 9 . . . . . number of nickels
