How do you find the minimum value when the average and the maximum are known?

Answer:
It helps if you know the definition of 'average' and can write it down.

Avg = 1/2 (MAX + min)

Eliminate the parentheses on the right side:

Avg = 1/2MAX + 1/2min

Subtract 1/2MAX from each side:

Avg - 1/2MAX = 1/2min

Multiply each side by 2:

2Avg - MAX = min

which is exactly what you're looking for.
