Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
An author of a book got 6% of the total sales of the paper cover version of his books and 12% of the total sales of the hardcover version. 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?

### Response:
 Mapato yote ya toleo la karatasi yalikuwa $0.20 x 32,000 = $<<0.20*32000=6400>>6,400.
Kwa hivyo, mwandishi alipata $6,400 x 6/100 = $384 kutoka kwenye toleo la karatasi.
Mapato yote ya toleo la kufunika ngumu yalikuwa $0.40 x 15,000 = $<<0.40*15000=6000>>6,000.
Kwa hivyo, mwandishi alipata $6,000 x 12/100 = $720 kutoka kwenye toleo la kufunika ngumu.
Hivyo, mwandishi alipata jumla ya $384 + $720 = $<<384+720=1104>>1,104.
