Answer 1

9514 1404 393

Answer:

• 16 quarters
• 9 nickels

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
