Tim o neetswe kwelobotlhoko go ya kwa maemong a a kwa godimo a a mo nayang koketsego ya 5% mo go P20000 e a e amogelang kgwedi le kgwedi.  Gape o amogela bonus e e lekanang le halofo ya tuelo ya kgwedi.  O tla bo a amogela bokae ka ngwaga?

Bob wants to dig a hole 6 feet long by 4 feet wide by 3 feet deep. If it takes him 3 seconds to shovel a cubic foot of earth, how long will it take him to dig the hole?
Kgolo ya maemo e dirile gore tuelo ya gagwe ya kgwedi le kgwedi e gole ka P20000*.05=P<<20000*0.05=1000>>1000
Ka jalo tuelo ya gagwe e ntsha e tla nna P20000+P1000=P<<20000+1000=21000>>21000 ka kgwedi
Ka jalo o tla bo a amogela P21000*12=P<<21000*12=252000>>252,000 ka ngwaga
Bonus e lekana le P21000*.5=P<<21000*.5=10500>>10500
Ka jalo o tla bo a amogela P252,000+P10,500=P<<252000+10500=262500>>262,500 ka ngwaga

The hole is 6 feet long by 4 feet wide by 3 feet deep or 6 * 4 * 3 = <<6*4*3=72>>72 cubic feet.
Bob shovels a cubic foot of earth every 3 seconds so it will take 72 * 3 = <<72*3=216>>216 seconds to dig the hole.
