How to calculate the market price of $1000 face value bond

Since it is bond with semiannual payments, hence, the number of discounting period is 2*9=18 and semiannaul coupon is 1,000*7%/2=$35. The market price = 35/(1+7.73%/2) + 35/(1+7.73%/2)^2 + 35/(1+7.73%/2)^3 + ..... + 35/(1+7.73%/2)^17 + 1,035/(1+ 7.73%/2)^18.
