Answer 3

you can use the formula

\[I = \frac{Prt}{100}\]

P = Principal, r = interest rate and t = time periods.

substitute and calculate the answer.


then add the principal and interest to get the total value.

in question 2, I'd assume the interest is per annum or per year. Which means the time of 9 months needs to be changes to years... 9 months = 0.75 years

hope it helps

then

total = 200 + the value for I you calculated above
