Sophia le Rose ba ile mmarakeng go reka dieie le dipotata. Rose o rekile dieie le dipotata tse di fetang tsa ga Sophia ka makgetlho a le mane. Fa e le gore Rose o rekile dieie di le 12 le dipotata di le 4, Sophia o rekile dieie le dipotata di le kae ka palo? 

Janet takes two bus trips five days a week. If each bus trip costs her $2.20, how much would she save by buying a weekly bus pass for $20?
Palo ya dieie tse di rekilweng ke Sophia ke 12 / 4 = <<12/4=3>>3.
Palo ya dipotata tse di rekilweng ke Sophia ke 4 / 4 = <<4/4=1>>1.
Ka jalo, palo yotlhe ya dieie le dipotata tse di rekilweng ke Sophia kwa mmarakeng ke 3 + 1 = <<3+1=4>>4.

First find the total number of trips Janet takes during the week: 2 trips/day * 5 days/week = <<2*5=10>>10 trips/week
Then multiply this number by the cost per trip to find her current weekly spending: 10 trips/week * $2.20/trip = $<<10*2.20=22>>22/week
Then subtract the cost of the weekly bus pass from this number to find her savings: $22/week - $20/week = $<<22-20=2>>2
