Lelapa la ga Alani le ne la swetsa gore bana ba kwale dipolelo tsa mofuta ope fela. Morago ga foo ba ne ba tshwanetse go bala dipolelo tsotlhe tse ba di kwadileng kwa pele ga lelapa kwa bokhutlong jwa mafelo a beke. Alani o ne a kwala dipolelo di le 20 mo bekeng ya ntlha, morwarraagwe Braylen a kwala dipolelo di le 40, mme kgaitsadiake Margot a kwala dipolelo di le 60. Fa mongwe le mongwe a ne a ka oketsa palo ya dipolelo tse a di kwadileng mo bekeng ya ntlha ka pedi mo bekeng ya bobedi, bala palo yotlhe ya dipolelo tse ba di kwadileng. 

Katerina makes designer jewelry.  Her specialty is topaz necklaces.  She uses 8 topaz gemstones per necklace, and fills the space between gemstones using sterling silver beads.  If each topaz gemstone is one inch long, each sterling silver bead is one-quarter of an inch long, and each necklace is made to a total length of 25 inches, how many sterling silver beads does Katerina use per necklace?
Mo bekeng ya ntlha, Alani o ne a kwala dipolelo di le 20, mme fa a ne a ka oketsa palo eo ka pedi mo bekeng ya bobedi, palo yotlhe ya dipolelo mo bekeng ya bobedi e nna 20*2 = <<20*2=40>>40.
Ka kakaretso, Alani o ne a kwaditse dipolelo di le 40+20 = <<40+20=60>>60 mo dibekeng tse pedi.
Braylen le ene o ne a kwala dipolelo di le 40 mo bekeng ya ntlha, mme fa a ne a ka oketsa palo eo ka pedi mo bekeng ya bobedi palo eo e ne ya nna 2*40 =<<40*2=80>>80
Palo yotlhe ya dipolelo tsa gagwe mo dibekeng tse pedi ke 80+40 = <<80+40=120>>120
Fa ba kopane, Alani le morwarraagwe Braylen ba ne ba kwaditse dipolelo di le 120+60 = <<120+60=180>>180. 
Fa Margot a ne a ka oketsa palo ya dipolelo tse a di kwadileng mo bekeng ya ntlha ka pedi mo bekeng ya bobedi, o ne a kwala dipolelo di le 2*60 = <<2*60=120>>120 mo bekeng ya bobedi. 
Ka kakaretso, o ne a kwaditse dipolelo di le 60+120= <<60+120=180>>180.
Fa ba kopane botlhe, bana ba le bararo ba ne ba kwaditse dipolelo di le 180+180 = <<180+180=360>>360 mo dibekeng tse pedi.

8 topaz gemstones, at 1 inch per gemstone, contribute a total of 8*1=<<8*1=8>>8 inches to each necklace.
Since each necklace is 25 inches in length, then there are 25-8=<<25-8=17>>17 inches of space between gemstones.
Since Katerina uses one-quarter inch sterling silver beads to fill space between gemstones, then she will require 17*4=<<17*4=68>>68 sterling silver beads per necklace.
