Fa Marcy a ka berekela khamphani e le nngwe dingwaga di le 40, o tla bona phenšene ya $50,000 ka ngwaga.  Fa a sena go bereka dingwaga di le 20, o tla simolola go bona 5% ya boleng jwa phenšene eo ngwaga le ngwaga. Fa a ka tlogela tiro eo a sena go bereka dingwaga di le 30, phenšene ya gagwe e tla bo e le bokae ka ngwaga?

If Marcy works for the same company for 40 years, she gets an annual pension of $50,000/year. Starting after 20 years, she becomes entitled to 5% of the value of the pension per year. If she quits after 30 years, what will her annual pension be?
Sa ntlha, bona gore Marcy o berekile dingwaga di le kae morago ga dingwaga di le 20: dingwaga di le 30 - dingwaga di le 20 = <<30-20=10>>dingwaga di le 10
Morago ga moo, atisa palo eo ka selekanyo sa phenšene ya gagwe e a e bonang ka ngwaga: dingwaga di le 10 * 5% = 50%
Morago ga moo, atisa peresente eo ka palogotlhe ya phenšene go bona gore o tla bona bokae: $50,000 * 50% = $<<50000*50*.01=25000>>25,000

First find how many years Marcy works after 20 years: 30 years - 20 years = <<30-20=10>>10 years
Then multiply that number by the amount of her pension she gets per year: 10 years * 5% = 50%
Then multiply that percentage by the total amount of the full pension to find how much she gets: $50,000 * 50% = $<<50000*50*.01=25000>>25,000
