<prompt> Bala sekhahla sa phaello haeba mosuoe-hlooho ke lidolara tse 80, lilemo tse 3 li fetile, me phaello ke 7.nan  <response>: Instruction in English: Calculate the rate of interest if the principal is 80 dollars, 3 years have elapsed, and the interest is 7. . Response in English: To calculate the rate of interest, we can use the formula: I PrtWhere:- I is the interest- P is the principal- r is the rate of interest in decimal form- t is time in yearsIn this case, we are given the principal P 80, time t 3 and interest I 7, but we are looking for the rate of interest r.Since the interest is given as 7, we can convert it to decimal by dividing by 100; thus, I 7100 0.07.Plugging the values into the formula, we have:0.07 80r3Solving for r:r 0.07803r 0.00029167The rate of interest is 0.029167 or approximately 0.03. . Response in Sesotho: Ho bala sekgahla sa tswala, re ka sebedisa foromo: I Prt Moo: - Ke tswala - P ke hlooho - r ke sekhahla sa tswala ka sebopeho sa decimal - t ke nako ka lilemo Tabeng ena, re fuoa mosuoe-hlooho P 80, nako t 3 le thahasello I 7, empa re batla tekanyo ea thahasello r. Kaha thahasello e fanoa e le 7, re ka e fetolela ho decimal ka ho arola ka 100; kahoo, ke 7100 0,07. Ho kenya litekanyetso ka hara foromo, re na le: 0.07 80 r 3 Ho rarolla r: r 0.07 80 3 r 0.00029167 Sekhahla sa phaello ke 0.029167 kapa hoo e ka bang 0.03.
