### Instruction:
 Jackson anasafisha kikasha chake cha barua pepe baada ya kugundua ana barua pepe nyingi ambazo hahitaji tena na anaweza kuzifuta. Wakati anasafisha kikasha chake, hata hivyo, anaendelea kupokea barua pepe zaidi. Wakati anafuta barua pepe 50, anapokea barua pepe nyingine 15. Wakati anafuta barua pepe 20 zaidi, anapokea barua pepe 5 zaidi. Baada ya kumaliza kufuta barua pepe zake za zamani, anabakiwa na barua pepe mpya tu, ikiwa ni pamoja na 10 zaidi ambazo alipokea. Kuna barua pepe ngapi katika kikasha cha Jackson sasa?


### Response:
 Jackson alifuta barua pepe zake za zamani, kwa hivyo sasa anabakiwa na zile mpya tu, ambazo kwanza alipokea 15 + 5 = 20.
Kisha Jackson anapokea barua pepe nyingine 10 kuongeza na zile 20 mpya, 10 + 20 = 30 barua pepe mpya.
Sasa Jackson ana barua pepe 30 mpya katika kikasha chake, maana yake ana jumla ya barua pepe 30 katika kikasha chake.
