Q. Nick has 80,000 \text{₹} 80,000 in a savings account that earns 6% 6\% interest per year. The interest is not compounded. How much interest will he earn in 11 year? Use the formula i=prt i = prt , where i i is the interest earned, p p is the principal (starting amount), r r is the interest rate expressed as a decimal, and t t is the time in years.
  1. Identify Values and Formula: Identify the values given in the problem and the formula to use.\newlineWe know:\newlinePrincipal pp = ₹ 80,00080,000\newlineInterest rate rr = 6%6\% per year\newlineTime tt = 11 year\newlineThe formula to calculate the interest is i=prti = prt.
  2. Convert Rate to Decimal: Convert the interest rate from a percentage to a decimal.\newlineTo convert a percentage to a decimal, divide by 100100.\newliner=6%=6100=0.06r = 6\% = \frac{6}{100} = 0.06
  3. Substitute Values into Formula: Substitute the values into the formula.\newlineUsing the formula i=prti = prt, we substitute the values we have:\newlinei=80,000×0.06×1i = 80,000 \times 0.06 \times 1
  4. Perform Multiplication: Perform the multiplication to find the interest.\newlinei=80,000×0.06×1i = 80,000 \times 0.06 \times 1\newlinei=4,800i = 4,800
