Jake o rekela diaparo kwa lebenkeleng. Lebenkele le na le tshwaelo ya re o reka hempe e nngwe o bone e nngwe ka 50% off. Jake o reka dihempe di le pedi. Tlhwatlhwa ya hempe e nngwe le e nngwe ke $8. Morago ga foo, Jake o reka dipara tsa ditlhako tse di fokoditsweng ka 40% go tswa go tlhwatlhwa ya ntlha. Tlhwatlhwa ya ntlha ya dipara tsa ditlhako ke $40. Ke bokae jotlhe boo Jake a bo dirisitseng kwa lebenkeleng?

Jackie grew 3" over the summer.  She is now 2" shorter than Anne, who is twice the size of Albert.  If Albert is 36" tall, how tall was Jackie before summer?
Tlhwatlhwa ya hempe morago ga 50% off ke $8 * 0.50 = $<<8*0.50=4>>4
Tlhwatlhwa ya dihempe ka bobedi ke $8 + $4 = $<<8+4=12>>12
Madi a a fokoditsweng go tswa go tlhwatlhwa ya ntlha ya dipara tsa ditlhako ke $40 * 0.40 = $<<40*0.4=16>>16
Tlhwatlhwa ya dipara tsa ditlhako morago ga thekiso ke $40 - $16 = $<<40-16=24>>24
Jotlhe ja madi a a dirisitsweng ke Jake kwa lebenkeleng ke $12 + $24 = $<<12+24=36>>36
#### 36 

Anne is twice the size of Albert, who is 36", so Anne is 2*36 = <<72=72>>72" tall
Anne is 72" tall and Jackie is 2" shorter than Anne, so Jackie is 72-2 = <<72-2=70>>70" tall
Jackie is currently 70" tall and grew 3" over summer, so before summer she was 70-3= <<70-3=67>>67" tall
