Jenna has 4 roommates. Each month the electricity bill is $100. How much will each roommate pay per year for electricity, if they divide the share equally?
O ananya di-sticker di le 27 tse dinnye ka gonne 30 x .9 = <<27=27>>27
O bona dikonopo di le 9 tse dikgolo ka tsone ka gonne 27 / 3 = <<27/3=9>>9
O ananya di-sticker di le 20 tse dikgolo ka dikonopo tse dikgolo ka gonne 40 x .5 = 20
O bona dikonopo di le 20 tse dikgolo ka tsone ka gonne 20 / 1 = <<20/1=20>>20
O ananya 50% ya di-sticker tsa gagwe tse dikgolo ka dikonopo tse dinnye ka gonne 100 - 50 = <<100-50=50>>50
O ananya di-sticker di le 20 tse dikgolo ka dikonopo tse dinnye ka gonne 40 x .5 = 20
O bona dikonopo di le 60 tse dinnye ka gonne 20 x 3 = <<20*3=60>>60
O na le dikonopo di le 89 kwa bofelong ka gonne 9 + 20 + 60 = <<9+20+60=89>>89

There are 12 months in a year, so the total electricity for the year will cost 100*12 =$<<100*12=1200>>1200.
Since there are 5 roommates, each roommate will pay 1200/5=$<<1200/5=240>>240 in a year.
