### Instruction:
 Kompyuta mpya ya John iligharimu $1500. Anahitaji kupata skrini na vifaa vingine ambavyo gharama yake ni 1/5 ya hiyo. Pia anataka kuboresha kadi ya video ya $300 katika kompyuta ya msingi na moja ambayo gharama yake ni mara mbili. Ameitumia kiasi gani?


### Response:
 Gharama ya kompyuta ya msingi ni $1500.
Skrini na vifaa vingine gharama yake ni 1/5 * $1500 = <<1/5*1500=300>>300 dola.
Kadi mpya ya video gharama yake ni 2 * $300 = <<2*300=600>>600 dola.
Jumla, amezitumia $1500 + $300 + $600 = <<1500+300+600=2400>>2400 dola.
