Sandy o tsamaile ka dinao go tswa kwa Holloway Shores go ya kwa Sun Valley Shores diura di le 8 mo letsatsing le le lengwe. O tsamaile gape halofo ya diura tse a di tsamaileng mo letsatsing la ntlha mo letsatsing la bobedi, a ya kwa Hollock valley shores. Bala nako yotlhe e Sandy a e tserego a tsamaya ka dinao mo malatsing a mabedi ka metsotso. 

Joe has twice as many cars as Robert. He sells 20% of them and gives away twice as many cars as the number he sold to his mother. If Robert has 20 cars, how many cars does joe remain with after selling and giving some to his mother?
Fa a tsamaile halofo ya diura tse a di tsamaileng mo letsatsing la ntlha mo letsatsing la bobedi, o tsamaile diura di le 1/2*8 = <<8*1/2=4>>4 mo letsatsing la bobedi.
Nako yotlhe e Sandy a e tsamaileng mo malatsing a mabedi ke diura di le 8+4 =<<8+4=12>>12.
Ka ge ura e le nngwe e na le metsotso e le 60, Sandy o tsamaile metsotso e le 12*60 = <<12*60=720>>720 mo malatsing a mabedi.
#### 720 

If Robert has 20 cars, and Joe has twice as many cars as Robert, Joe has 2*20 = 40 cars.
He then sells 20/100*40=<<20/100*40=8>>8 cars from his car collection.
After selling 8 cars, Joe remains with 40-8=<<40-8=32>>32 cars.
Joe then gives away twice as many cars as the number he sold to his mother, a total of 2*8=<<2*8=16>>16 cars.
The number of cars that Joe has remaining after giving 16 cars to his mother is 32-16=<<32-16=16>>16
#### 16
