Q. Oliver has ₹60 in a savings account that earns 10% interest per year. The interest is not compounded. How much interest will he earn in 4 years? Use the formula i=prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Identify values: Identify the principal amount, interest rate, and time.Principal p = ₹60Interest rate r = 10% per yearTime t = 4 yearsConvert the interest rate from a percentage to a decimal for the calculation.r=10%=10010=0.10
Convert interest rate: Use the formula i=prt to calculate the interest.i=p×r×ti=60×0.10×4
Calculate interest: Perform the multiplication to find the interest.i=60×0.10×4i=60×0.4i=₹24
