### Instruction:
There are 381 pages in Elliot’s book.  He has already read 149 pages.  If he reads 20 pages a day for a week, how many pages are still left to be read?

### Response:
 Kwa wiki, Elliot atasoma kurasa 20 x 7 = <<20*7=140>>140.
Kwa kuongeza kusoma awali, amesoma jumla ya kurasa 149 + 140 = <<149+140=289>>289.
Kuna kurasa 381 - 289 = <<381-289=92>>92 zimesalia kusomwa.
