Ba rekile kuku e e lopang $11. Gape ba rekile diboloone di le dozen tse di neng di rekisiwa ka $0.5 ya di le 2. Madi a a setseng ba a dirisitse go reka maeisekirimu a le 2 a a lopang $7 se sengwe le se sengwe. Mme wa ga Julia le Nadine o ne a file mongwe le mongwe wa bone bokae?

Jon's car needs a tune-up every 1000 miles.  He drives 100 miles a day for a 30 day month.  How many tune-ups does he need in that time?
Go na le dipara tsa diboloone di le 12/2 = <<12/2=6>>6 mo go dozen.
Tlhwatlhwa ya go reka dozen ya diboloone e ne e le $0.5 x 6 = $<<0.5*6=3>>3.
Tlhwatlhwa ya maeisekirimu a le 2 e ne e le $7 x 2 = $<<7*2=14>>14.
Tlhwatlhwa yotlhe ya dilo tse ba di rekileng ke $11 + $3 +$14 = $<<11+3+14=28>>28.
Ka jalo mme wa bone o file mongwe le mongwe wa bone $28/2 = $<<28/2=14>>14.

He drives 100*30=<<100*30=3000>>3000 miles
So he needs 3000/1000=<<3000/1000=3>>3 tune-ups
