How would I go about solving for ' i '?

Steps would be greatly appreciated. Thank you

KatyDid Clothes has a $150 million (face value) bond issue selling for 104 percent of par that carries a coupon rate of 11 percent, paid semiannually. What would be Katydid's before-tax component cost of debt? Solving equation 11-5 for iD: Solve {$1, 040 = $55 times[1- 1/(1+i_D)^40/i_D] + $1,000/(1+i_D)^40} for i_D
