The total earnings for the paper cover version were $0.20 x 32 000 = $<<0.20*32000=6400>>6,400.

So, the author earned $6,400 x 6/100 = $384 from the paper cover version.

The total earnings for the hardcover version were $0.40 x 15,000 = $<<0.40*15000=6000>>6,000.

So, the author earned $6,000 x 12/100 = $<<6000*12/100=720>>720 from the hardcover version.

Therefore, the author earned a total of $384 + $720 = $<<384+720=1104>>1104.

If 32,000 copies of the paper cover version were sold at $0.20 each and 15,000 copies of the hardcover version were sold at $0.40 each, how much did the author earn?
