Sejana sa aeskerimi se se jang R13 jaanong se rekisiwa ka R11. Phakethe ya mashi e ne e rekisiwa ka theolelo ya R0.5. O tla boloka bokae fa o reka dijana tsa aeskerimi di le 2 le dipakethe tsa mashi di le 4?

Sandy wants to lose as much weight as Joey does but needs 4 weeks to lose the same amount of weight that Joey loses in a single week. If Joey loses 8 pounds in 4 weeks, how many weeks will it take Sandy to lose the same amount of weight?
Theolelo ya sejana se le sengwe sa aeskerimi ke R13 - R11 = R<<13-11=2>>2.
Ka jalo theolelo ya dijana tsa aeskerimi di le 2 ke R2 x 2 = R<<2*2=4>>4.
Theolelo yotlhe ya dipakethe tsa mashi di le 4 ke R0.5 x 4 = R<<0.5*4=2>>2.
O tla boloka R4 + R2 = R6 fa o reka dijana tsa aeskerimi di le 2 le dipakethe tsa mashi di le 4.

Joey loses 8 pounds / 4 weeks = <<8/4=2>>2 pounds per week.
In order to match Joey, Sandy should lose 2 pounds / 4 = <<2/4=0.5>>0.5 of a pound per week.
To find the number of weeks it will take, divide the number of pounds by the rate of weight loss: 8 pounds / 0.5 pounds/week = <<8/0.5=16>>16 weeks
