Feme e ne e tlhola e dira diterekera, mme jaanong e dira disailo. Fa ba ne ba dira diterekera, ba ne ba rekisa diterekera di le 10 ka letsatsi mme ba bona P100 ka tereketara. Jaanong, ba rekisa disailo di le 5 ka letsatsi, mme ba bona P220 ka sailou.  Ba dira diperesente di le kae go feta jaanong ka letsatsi?

Jenny buys 1 bag of cookies a week.  The bag has 36 cookies and she puts 4 cookies in her son's lunch box 5 days a week.  Her husband eats 1 cookie a day for 7 days.  Jenny eats the rest of the cookies.  How many cookies does Jenny eat?
Ba ne ba tlhola ba bona P1,000 ka letsatsi ka gonne 10 x 100 = <<10*100=1000>>1,000
Jaanong ba bona P1,100 ka letsatsi ka gonne 5 x 220 = <<5*220=1100>>1,100
Ba dira 10% go feta ka letsatsi ka gonne 1000 +(1000 x (X/100)) = 1,100 fa X = 10
#### 10

The son gets 4 cookies a day for 5 days so he eats 4*5 = <<4*5=20>>20 cookies
Her husband eats 1 cookie a day for 7 days so he eats 1*7 = <<1*7=7>>7 cookies
There are 36 cookies in a bag and her son eats 20 and her husband eats 7 so Jenny eats 36-20-7 = <<36-20-7=9>>9 cookies
