Calculating Total Repayment Amount with Simple Interest
The question in the image is about calculating the amount of money a woman must repay after 4 years, having borrowed $26,000 at a simple interest rate of 1.9%. Simple interest can be calculated using the formula: \[ \text{Simple Interest (SI)} = \text{Principal (P)} \times \text{Rate (R)} \times \text{Time (T)} \] Where: P is the principal amount (the initial amount borrowed) R is the rate of interest per period (in decimal form) T is the time the money is borrowed for Given: P = $26,000 R = 1.9% per year (which is 0.019 in decimal form) T = 4 years First, calculate the interest (I): \[ I = P \times R \times T \] \[ I = 26000 \times 0.019 \times 4 \] \[ I = 1972 \] She will accumulate $1,972 in interest over 4 years. To find the total amount she must repay, you add the interest to the principal: \[ \text{Total Amount} = \text{Principal} + \text{Interest} \] \[ \text{Total Amount} = 26000 + 1972 \] \[ \text{Total Amount} = 27972 \] So, the woman must repay a total of $27,972 after 4 years.
Calculating Simple Interest and Total Repayment Amount
The question involves calculating the simple interest and then determining the total amount of money that the woman has to repay after 4 years. The formula for calculating simple interest is: \( I = P \times r \times t \) where \( I \) is the interest, \( P \) is the principal amount (initial loan amount), \( r \) is the annual interest rate (in decimal form), \( t \) is the time the money is borrowed for, in years. According to the image, the woman borrows $26,000, the interest rate is 3.9%, and the time is 4 years. First, convert the interest rate from a percentage to a decimal by dividing by 100: \( r = 3.9\% = \frac{3.9}{100} = 0.039 \) Now plug the numbers into the formula: \( I = P \times r \times t \) \( I = 26000 \times 0.039 \times 4 \) Now calculate the interest: \( I = 26000 \times 0.039 \times 4 \\ I = 1016 \times 4 \\ I = 4064 \) The interest that will be accrued over 4 years is $4,064. Next, to find the total amount that must be repaid, add the interest to the principal amount: \( Total = P + I \) \( Total = 26000 + 4064 \) \( Total = 30064 \) The woman will have to repay a total of $30,064 after 4 years.
