Final answer:
The question refers to calculating the size of two equal loan payments that Ruby needs to make, considering a 2% interest rate. The payments need to be discounted to present value to solve for the equal payment amount. However, the exact answer requires additional information on interest calculations and compounding periods.
Step-by-step explanation:
When Ruby borrowed $51,130.00, she agreed to repay the loan in two equal payments to be made 50 days and 80 days from the day the money was borrowed. If interest is 2% on the loan, to find the size of the equal payments using today as a focal date, we need to calculate the present value of the repayments. The key is to adjust those future payment amounts back to their present value considering the time value of money and the specified rate of interest.
Using the present value formula for each payment:
- PV = P / (1 + r)^n where PV is the present value, P is the payment amount, r is the interest rate per period, and n is the number of periods. We calculate the present values and solve for P, ensuring that the sum of the present values equals the loan amount of $51,130. Once we find P, that amount will be the value of the equal payments Ruby needs to make.
However, since the provided reference information does not include specific formulas related to the loan Ruby obtained, and the calculation for her payment scenario is complex, the exact answer to the size of the equal payments cannot be given without further information on how the interest is applied (e.g., simple or compound), and the number of compounding periods.
