Mo kamoreng, go na le ditshamekisi tse di farologaneng: dikoloi tse di khibidu di le 5, action figures di le 3, le popi e le 1. Popi e ja madi a a lekanang le a action figures di le 3 mme koloi e khibidu e le nngwe e ja R4. Ditshamekisi tsotlhe di ja bokae, fa action figure e ja R5? 

If a bag of marbles costs $20 and the price increases by 20% of the original price every two months, how much would a bag of marbles cost after 36 months?
Action figures di le tharo di ja R3 * 5 = R<<3*5=15>>15, tse di lekanang le popi.
Dikoloi tse di khibidu di ja R5 * 4 = R<<5*4=20>>20. 
Ka jalo ditshamekisi tsotlhe di ja R20 + R15 + R15 = R<<20+15+15=50>>50.

When the price of the bag of marble increase by 20%, the price increases by 20/100*20 = $<<20/100*20=4>>4
If the price increases after every two months, in 36 months, it will increase 36/2 = <<36/2=18>>18 times.
If each increase is $4, the total amount the price of the bag of marbles will have increased by after 36 months is 18*$4 = $<<18*4=72>>72
After the total increase of the price of the bag of marbles after 36 months, the total cost will be $20+$72 = $<<20+72=92>>92
