Lauren o boloka 20% ya tuelo nngwe le nngwe ya gagwe. Ke dingwaga di le kae gape tse Lauren a tlhokang go di bereka fa a ikaelela go boloka nako ya dingwaga di le 20 ya go rola tiro, a tshela ka 40% ya tuelo ya gagwe ya ngwaga le ngwaga e a e amogelang gompieno, mme tuelo ya gagwe ya gompieno ke $100,000?

A jellyfish tank has numerous jellyfish in it. A fifth of the jellyfish are large, and a third of the large jellyfish change color from green to blue under UV light. The other jellyfish are small and always stay blue. When a UV light turned on, 6 jellyfish changed color. How many jellyfish are in the tank?
Lauren o ikaelela go tshela ka 40% ya tuelo ya gagwe ya gompieno ($100,000) fa a sena go rola tiro, ka jalo 40%*$100,000 = $<<40*.01*100000=40000>>40,000
Fa a batla go boloka dingwaga di le 20, o tla tlhoka go boloka 20 * $40,000 = $<<20*40000=800000>>800,000 go rola tiro
Fa tuelo ya gagwe ya gompieno e le $100,000 mme a boloka 20%, o kgona go boloka $100,000 * 20% = $<<100000*20*.01=20000>>20,000 ngwaga le ngwaga
Go fitlhelela maikaelelo a gagwe a go boloka ($800,000) o tla tlhoka go bereka dingwaga tse dingwe gape $800,000/$20,000 = <<800000/20000=40>>40

A third of the large jellyfish change color, so there are 6 * 3 = <<6*3=18>>18 large jellyfish.
A fifth of the jellyfish are large, so there are 18 * 5 = <<18*5=90>>90 jellyfish in the tank.
