Kris o leka go fitlhelela mokgele wa motshameko wa bidio wa go tshameka diura di le 30. Fa Kris a tshameka halofo ya ura letsatsi le letsatsi ka dibeke di le 2 mme a bo a tshameka diura di le 2 letsatsi le letsatsi ka beke e le nngwe, o sa ntse a tlhoka go tshameka diura di le kae gore a fitlhelele mokgele?

At Ashley's school, they start a reforestation campaign where each child plants a tree and each teacher plants 2 trees. The school has 40 classes with an average of 25 students and 3 teachers per class. How many trees will they have planted at the end of the campaign?
Dibeke di le pedi di tshwana le dibeke di le 2 * malatsi a le 7 = <<2*7=14>>malatsi a le 14.
Ka jalo go tshameka halofo ya ura letsatsi le letsatsi go raya gore Kris o tla bo a tshamekile diura di le 0.5 * malatsi a le 14 = <<0.5*14=7>>diura di le 7.
Go tshameka diura di le 2 letsatsi le letsatsi ka beke e nngwe e tla nna diura tse di oketsegileng di le 2 * malatsi a le 7 = <<2*7=14>>diura di le 14.
Ka jalo o sa ntse a tlhoka go tshameka 30 – 7 – 14 = <<30-7-14=9>>diura di le 9.

40 classes participate in the campaign, representing a total of 40 * 25 = <<40*25=1000>>1000 students.
With 3 teachers per class, 40 * 3 = <<40*3=120>>120 teachers participate.
With one tree planted per student, 1000 * 1 = <<1000*1=1000>>1000 trees are planted per student.
With 2 trees planted per teacher, 120 * 2 = <<120*2=240>>240 trees are planted per teacher.
Adding the trees planted by teachers and students, 1000 + 240 = <<1000+240=1240>>1240 trees will have been planted at the end of the campaign.
