James o rekile palamonwana ya lenyalo. Taemane e ne e le $600 mme gauta e le $300.  O duela 30% godimo ga tlhwatlhwa ya go e dira.  O duetse bokae gotlhe?

Kris is trying to earn a video game achievement for playing a total of 30 hours. If Kris plays for half an hour every day for 2 weeks then plays for 2 hours every day for a week, how many hours does she still need to play to earn the achievement?
Ditsompelo tsa palamonwana di lopile 600+300=$<<600+300=900>>900
Godimo ga tlhwatlhwa e ne e le 900*.3=$<<900*.3=270>>270
Ka jalo tlhotlhwa yotlhe e ne e le 900+270=$<<900+270=1170>>1170

Two weeks is the same as 2 weeks * 7 days = <<2*7=14>>14 days.
So playing for half an hour every day means Kris will have played for 0.5 hours * 14 days = <<0.5*14=7>>7 hours.
Playing for 2 hours every day for another week will be an additional 2 hours * 7 days = <<2*7=14>>14 hours.
She therefore still needs to play 30 – 7 – 14 = <<30-7-14=9>>9 hours.
