Answer: The first improvement cut the time by 32 * 0.08 = 2.56 minutes.

So, the new time after the first improvement is 32 - 2.56 = 29.44 minutes.

The second improvement cut the time by 29.44 * 0.05 = 1.472 minutes.

So, the final time is 29.44 - 1.472 = 27.968 minutes.

Rounding to the nearest minute, it now takes 28 minutes to manufacture the piece.
