could you help me with 11% and 9% thank you

Assuming that the current interest rate is 10 percent, compute the present value of a five-year, 10 percent coupon bond with a face value of $1,000. What happens when the interest rate goes to 11 percent? What happens when the interest rate goes to 9 percent? Instructions: Enter your responses rounded to the nearest penny (two decimal places). Do not round intermediate calculations. PV at an interest rate of 10%=$ PV at an interest rate of 11%=$ The present value when the interest rate rises to 11 percent. PV at an interest rate of 9%=$ The present value when the interest rate falls to 9 percent
