Mo bodibaneng jwa ga Tate go na le di-guppy tse ditonanyana di le 4, di-guppy tse di namagadi di le 7, di-goldfish tse ditonanyana di le 3, le di-goldfish tse di namagadi di le 5.  O reka di-guppy tse ditonanyana di le 2, se-guppy se se namagadi se le 1, di-goldfish tse ditonanyana di le 2, le di-goldfish tse di namagadi di le 3.  O na le ditlhapi tse di namagadi di feta tse ditonanyana ka di le kae?

Last year there were 50 students enrolled in a calligraphy class. This year, there was a 20% increase in enrollment. How many students are enrolled this year in the calligraphy class?
Tate o na le palogotlhe ya 4 + 3 = <<4+3=7>>7 ya ditlhapi tse ditonanyana.
O na le palogotlhe ya 7 + 5 = <<7+5=12>>12 ya ditlhapi tse di namagadi. 
Morago ga go reka, o nna le 7 + 2 + 2 = <<7+2+2=11>>11 ya ditlhapi tse ditonanyana.
Morago ga go reka, o nna le 12 + 1 + 3 = <<12+1+3=16>>16 ya ditlhapi tse di namagadi.
Mo bodibaneng jwa gagwe, go na le ditlhapi tse di namagadi di feta tse ditonanyana ka 16 - 11 = <<16-11=5>>5.
#### 5

There was an increase of 50 x 20/100 = <<50*20/100=10>>10 students in enrollment.
