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

### Instruction:
 Jason spent 1/4 of his money and an additional $10 on some books. He then spent 2/5 of the remaining money and an additional $8 on some DVDs. If he was left with $130, how much money did he have at first?


### Response:
 Sea X el dinero que Jason tenía al principio.
Jason gastó 1/4*X + 10 en libros.
Jason gastó 2/5*[X - (1/4*X + 10)] + 8 en algunos DVDs.
Jason tiene X - (1/4*X + 10) - {2/5*[X - (1/4*X + 10)] + 8} = $130 restantes.
X - 1/4*X - 10 - 2/5*X + 1/10*X + 4 - 8 = $130.
9/20*X - 14 = $130.
X = $320.
