Answer:

  • 0 quarters
  • 28 nickels

Step-by-step explanation:

Let d represent the number of dimes. Then 40-d is the number of nickels. The value is ...

  0.10d +0.05(40 -d) = 2.60

  0.05d = 0.60 . . . . . subtract 2.00

  d = 0.60/0.05 = 12 . . . . . the number of dimes

  40 -d = 40 -12 = 28 . . . . .the number of nickels
