Jerry o na le motlhape wa dikgogo. Dikgogo tse dihibidu di beela mae a le 3 ka letsatsi, mme tse ditshweu di beela mae a le 5 ka letsatsi. Letsatsi le letsatsi Jerry o kgobokanya mae a le 42. Fa a na le dikgogo tse ditshweu di le pedi go feta tse dihibidu, o na le dikgogo tse dihibidu di le kae?

Sara wants to buy herself a new jacket and 2 pairs of shoes. The jacket she wants costs $30 and each pair of shoes cost $20. Sara babysits the neighbor's kids 4 times, earning $5 each time she babysits them. Her parents pay her $4 each time she mows the lawn. If Sara already had $10 saved before she started babysitting, how many times must she mow the lawn before she can afford the jacket and shoes?
Sa ntlha, tlhomamisa equation ya palo ya mae a dikgogo di a beelang ka letsatsi: 3r + 5w = 42, moo r e leng palo ya dikgogo tse dihibidu mme w e le palo ya dikgogo tse ditshweu.
Morago ga foo, tlhalosa r go ya ka w go ya ka tshedimosetso e e mo potsoloseng: w = r + <<+2=2>>2
Jaanong tsenya r + 2 mo boemong jwa w mo equation ya palo ya mae: 3r + 5(r + 2) = 42
Jaanong atisa 5 ka se se mo masakaneng: 3r + 5r + 10 = 42
Jaanong tlhakanya di-term tse di tshwanang go bona 8r + 10 = 42
Jaanong ntsha 10 mo matlhakoreng oomabedi a equation: 8r = 32
Kgabagare, arola matlhakore oomabedi a equation ka 8 go bona r = 4

Both pairs of shoes will cost a total of 2 * $20 = $<<2*20=40>>40.
Sara will need to save a total of $30 + $40 = $<<30+40=70>>70 to buy everything that she wants.
Sara has earned 4 * $5 = $<<4*5=20>>20 from babysitting.
Between her savings and the babysitting, Sara has already saved $10 + $20 = $<<10+20=30>>30.
Sara needs to earn an additional $70 - $30 = $<<70-30=40>>40 from mowing the lawn to afford her clothes.
Sara must mow the lawn $40 / $4 = <<40/4=10>>10 times to afford to buy the jacket and shoes.
