You purchase a bond with a coupon rate of 8.2 percent, a par value of $1,000, semiannual coupons, and a clean price of $880. If the next coupon payment is due in three months, what is the invoice price? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

I'm not sure what I am doing wrong, but I keep getting 41 for the answer and this isn't correct.
