Ones of each coin would be 40¢, so this is equivalent to asking how you can make 35¢ using any number of each of those coins.

1Q + 1D = 35¢

1Q + 2N = 35¢

3D + 1N = 35¢

2D + 3N = 35¢

1D + 5N = 35¢

7N = 35¢

Add one of each coin and you get the solutions for 75¢.

2Q + 2D + 1N = 75¢

2Q + 1D + 3N = 75¢

1Q + 3D + 2N = 75¢

1Q + 3D + 4N = 75¢

1Q + 2D + 6N = 75¢

1Q + 1D + 8N = 75¢
