Mel o dirisa sesutlhatsi sa mowa se dirisang di-watt di le 900 ka diura di le 8 ka letsatsi. Seno se raya gore ura nngwe le nngwe sesutlhatsi seno se dirisa di-watt di le 900 tsa maatla a motlakase. Fa a fokotsa nako e a e dirisang ka diura di le 5 ka letsatsi, o tla bo a bolokile di-kilowatt di le kae tsa maatla a motlakase mo malatsing a le 30?

A builder works for 4 weeks every month and for 6 days every week. If he gets paid $50 every day, how much does he earn if he works for a year?
Sesutlhatsi sa mowa se dirisa di-watt di le 900 x 8 = <<900*8=7200>>7200 ka diura di le 8 ka letsatsi.
Sesutlhatsi sa mowa se dirisa di-watt di le 900 x 5 = <<900*5=4500>>4500 ka diura di le 5 ka letsatsi.
Jalo he, Mel o boloka di-watt di le 7200 - 4500 = <<7200-4500=2700>>2700 ka letsatsi.
Seno ke di-kilowatt di le 2700/1000 = <<2700/1000=2.7>>2.7 ka letsatsi ka gonne kilowatt e le nngwe e lekana le di-watt di le 1000.
Ka jalo he, mo malatsing a le 30 o tla bo a bolokile di-kilowatt di le 2.7 x 30 = <<2.7*30=81>>81 tsa maatla a motlakase.

The builder works for 6 days every week and works for 4 weeks every month so he works for 6 days/week * 4 weeks/month = <<6*4=24>>24 days/month
If he earns $50 every day he then earns $50/day * 24 days/month = $<<50*24=1200>>1200/month
A year is equal to 12 months so every year he earns $1200/month * 12 months/year = $<<1200*12=14400>>14400
#### 14400
