Ba lelapa la ga Llesis ba tsamaile ka koloi le go tsamaya ka dinao diura di le 6 go ya kwa lefelong la boikhutso la bone.  Ba ne ba kgweetsa ka lobelo lo lo tlwaelegileng la dikilometara di le 50 ka ura mme ba tsamaya ka dinao ka lobelo lo lo tlwaelegileng la dikilometara di le 5 ka ura go le kwa tlase ga halofo ya lobelo la bone fa ba kgweetsa. Fa go ba tsere diura di le 1.5 go tsamaya ka dinao, ke sekgala se se kana kang go ya kwa lefelong la bone la boikhutso?

Mike decides he wants to replace his movie collection with digital versions.  He has 600 movies.  A third of the movies are in various series and he knows he can get those for only $6 of the cost of a normal movie by just buying the series together.  40% of the remaining movies are older movies which are $5.  How much does replacing the movies cost if a normal movie costs $10?
Halofo ya lobelo lo lo tlwaelegileng la ba lelapa la ga Llesis fa ba kgweetsa ke 50/2 = <<50/2=25>>25 dikilometara ka ura.
Ka jalo, lobelo la bone lo lo tlwaelegileng fa ba tsamaya ka dinao e ne e le 25 - 5 = <<25-5=20>>20 dikilometara ka ura.
Jalo, ba tsamaile ka dinao sekgala sa 20 x 1.5 = <<20*1.5=30>>30 dikilometara.
Go ba tsere palogotlhe ya 6 - 1.5 = <<6-1.5=4.5>>4.5 diura ba kgweetsa.
Jalo, ba kgweetsitse sekgala sa 50 x 4.5 = <<50*4.5=225>>225 dikilometara.
Ka jalo, lefelo la bone la boikhutso le ne le le sekgala sa 30 + 225 = <<30+225=255>>255 dikilometara.

There are 600/3=<<600/3=200>>200 movies in series
So he pays 200*6=$<<200*6=1200>>1200
He has 600-200=<<600-200=400>>400 movies not in series
400*.4=<<400*.4=160>>160 movies are old
So those cost 160*5=$<<160*5=800>>800
400-160=<<400-160=240>>240 movies are neither old nor in series
They cost 240*10=$<<240*10=2400>>2400
So the total cost is 1200+800+2400=$<<1200+800+2400=4400>>4400
#### 4400
