Nishi invests £4300 at %5 interest a per year, how much will she have after 2 years

Nishi would have 4,740.75 because with problems like these you multiply the decimal value of the percent with the money value then add it to it. So 4300*0.05 = 215, 4300 + 215 = 4515 and then 4515*0.05 = 225.75, 4515 + 225.75 = 4740.75.
