I believe it would be 8 sense the other half is 4
Ok to find this answer you first have to subtract the 16 from the 30 to find what "CB" is, which is 14. From there subtract 14 and 16 from 49 to find that the whole answer is 35. I think that is the answer but I'm not positive.
Por un sistema de ecuaciones, tiene-se que:
- Cada lapiz cuesta 20 ptas.
- Cada boligrafo cuesta 50 ptas.
-------------------------
- Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.
- <u>Boligrafo cuesta 30 mas que un lapiz</u>, o sea,

- <u>8 boligrafos y 15 lapices cuesta 700</u>, o sea,

-------------------------
- Aplicando el <u>primer ecuación en la segunda, </u>tiene-se el cuesto de cada lapiz:






Cada lapiz cuesta 20 ptas.
-------------------------
Por fin, el cuesto de cada boligrafo es dado por:

Cada boligrafo cuesta 50 ptas.
