Q. Practice1-1: Simple \& Compound Interest\newlinePractice score: 1/181/15 1 / 18 \quad 1 / 15 answered\newlineQuestion 22\newlineJoy invests $8,000 \$ 8,000 at 13% 13 \% simple interest for 11 year. How much is in the account at the end of the 11 year period?\newlineAnswer: $ \$
  1. Calculate Simple Interest: We have:\newlinePrincipal amount (P): $8,000\$8,000\newlineInterest rate (r): 13%13\%\newlineTime period (t): 11 year\newlineSimple interest formula: I=P×r×tI = P \times r \times t\newlineCalculate the simple interest earned in 11 year.\newlineI=8000×13100×1I = 8000 \times \frac{13}{100} \times 1\newline= 8000×0.138000 \times 0.13\newline= $1040\$1040
  2. Calculate Total Amount: We have:\newlinePrincipal amount (P): $\$88,000000\newlineInterest earned (I): $\$10401040\newlineCalculate the total amount in the account at the end of 11 year.\newlineTotal amount = Principal amount + Interest earned\newline= 8000+10408000 + 1040\newline= $\$90409040
