### Instruction:
The new pad of paper has 120 pages. Sammy uses 25% of the pages for his science project, and another 10 pages for his math homework. How many pages remain in the pad?

### Response:
 Alitumia 120 * 0.25 = <<120*0.25=30>>30 kwa sayansi.
Kulikuwa na kurasa 120 - 30 = <<120-30=90>>90 zilizosalia.
Kisha alikuwa na kurasa 90 - 10 = <<90-10=80>>80 zilizosalia.
