Morago ga go fa bana ba gagwe ba le barataro rolo e le nngwe mongwe le mongwe, a roba serepa sengwe le sengwe sa dirolo tse di setseng ka dikarolwana di le robedi (8) mme a di fepa dikoko. O fepile dikoko dikarolwana di le kae tsa dirolo?

A company bought $400000 worth of equipment from a retailer business, but pieces of equipment worth 40% of the total number were faulty. If they returned the faulty pieces of equipment to the seller, calculate the total amount of money spent on functioning pieces of equipment.
Morago ga go fepa bana ba gagwe, Mme Sherman o ne a saletswe ke dirolo di le 12 - 6 = <<12-6=6>>6 
O fepile dikoko dikarolwana tsa dirolo di le 6 x 8 = <<6*8=48>>48.
#### 48

If 40% worth of the pieces of equipment bought were faulty and were returned, the amount of money they were bought for is 40/100*$400000 = $<<40/100*400000=160000>>160000
Since the faulty pieces of equipment were worth $400000, the functioning equipment was worth $400000-$160000 = $<<400000-160000=240000>>240000
#### 240000
