- Equity in a Home When you purchase a home by securing a mortgage, the total paid toward the principal is your equity in the home. Technically, the lending agency calculates your equity by subtracting the amount you still owe on your mortgage from the current value of your home, which may be higher or lower than your principal. Assume that your mortgage is for 350, 000 at a monthly rate of 0.007 as a decimal and that the term of the mortgage is 30 years. Then your equity after k monthly payments is 350, 0001.007k-11.007360-1 dollars. Calculate the equity in your home after 10 years.arrow_forwardMonthly Savings Program Alice opens a savings account that pay 3% interest per year, compounded monthly. She begins by depositing $100 at the start of the first month and add $100 at the end of each month, when the interest is credited. Find a recursive formula for the amount An in her account at the end of the nth month. (Include the interest credited for that month and her monthly deposit.) Find the first five terms of the sequence An . Use the pattern you observed in (b) to find a formula for An . [Hint: To find the pattern most easily, it’s best not to simplify the terms too much.] How much has she saved after 5 years?arrow_forwardInterest Rate An item at a department store is priced at 189.99 and can be bought by making 20 payments of 10.50. Find the interest rate, assuming that interest is compounded monthly.arrow_forward
