  32 coins

  consider the value of a group of coins

Step-by-step explanation:

The coins are in equal numbers, so they can be considered as a group. The value of one group of 4 coins is ...

  1¢ + 5¢ + 10¢ + 25¢ = 41¢ = $0.41

Then the number of groups (g) of coins is ...

  $3.28 = $0.41×g

  g = $3.28/$0.41 = 8

There are 8 groups of coins. Each group has 4 coins, so there are ...

  (8 groups)×(4 coins/group) = 32 coins
