Khampani ya Hortex e dira dijusi tsa carrot tse tshetsweng ka dibotlolo. Letsatsi le letsatsi ba kgona go dira dibotlolo di le 4200 tsa dijusi tse. Jusi e nngwe le e nngwe e kgona go thusa 20% ya tlhokego ya letsatsi le letsatsi ya maatla a motho a le mongwe. Ke dibotlolo di le kae tse dingwe tse di tlhokegang go tlhagiswa ke Hortex gore ba kgone go kgotsofatsa 100% ya tlhokego ya letsatsi le letsatsi ya maatla a batho ba le 2300?

Linus works for a trading company. He buys a mobile device for $20 and sells it for twice the amount of the original price. If he bought 2 devices last Monday and 4 devices last Tuesday, how much profit was he able to earn after selling all the mobile devices he bought last Monday and Tuesday?
Jusi e nngwe le e nngwe e thusa 20% ya tlhokego ya letsatsi le letsatsi ya maatla, go raya gore go thusa 100%, motho a le mongwe o tla tlhoka 100 / 20 = <<100/20=5>>5 dijusi.
Go raya gore batho ba le 2300 ba tlhoka 5 * 2300 = <<2300*5=11500>>11500 dijusi go dira se.
Go kgona go thusa 100% ya tlhokego ya letsatsi le letsatsi ya maatla a batho ba le 2300, Hortex e tla tlhoka go dira dibotlolo di le 11500 - 4200 = 7300 tsa dijusi.
#### 7300 

The total cost for the devices he bought on Monday is 2*20= <<2*20=40>>40
The total cost for the devices he bought on Tuesday is 4*20 = <<4*20=80>>80
The total cost of these devices is 80+40= <<80+40=120>>120
Linus sold each mobile device he bought for $20 x 2 = $<<20*2=40>>40.
So, he earned $40 x 2 = $<<40*2=80>>80 for the two devices he bought last Monday.
And he earned $40 x 4 = $<<40*4=160>>160 for the 4 devices he bought last Tuesday.
The total amount of sales he made were worth 160+80 =<<160+80=240>>240
Linus earned 240-120 =$<<240-120=120>>120
