Tom o batla go tseisa mosadi wa gagwe loeto la segopotso sa lenyalo la bona.  Dithekete tsa sefofane di ja $5000 se tee.  Hotele e ja 20% go feta ka tlwaelo ka gonne ke mafelo a beke a a tlhanaselang.  Tlhwatlhwa e e tlwaelegileng ke $1500 ka letsatsi.  Fa ba nna koo malatsi a le 3 ke bokae loeto lo lo ba jeleng?

Nine of the kids in Gina's class are allergic to dairy, 6 are allergic to peanuts and 3 are allergic to both. If there are 32 kids in her class, how many aren't allergic to anything?
Kamore ya hotele e ja $1500*.2=$<<1500*.2=300>>300 go feta ka bosigo go feta ka tlwaelo
Ka jalo ba duela $1500+300=$<<1500+300=1800>>1800 ka bosigo
Seo se raya gore o duela $1800*3=$<<1800*3=5400>>5400
Dithekete tsa sefofane di ja $5000*2=$<<5000*2=10000>>10,000
Ka jalo tlhotlhwa yotlhe ke $10,000+5400=$<<10000+5400=15400>>15,400
#### 15400 

First subtract the number of kids who are allergic to each item from the total number of kids: 32 kids - 6 kids - 9 kids = <<32-6-9=17>>17 kids
Then add the number of kids who were double-counted because they're allergic to both things: 17 kids + 3 kids = <<17+3=20>>20 kids
