Answer:
coupon interest rate that the company must set on the bonds in order to sell the bonds-with-warrants at par is 8.25%.
Explanation:
warrant per share = 2*75 = $150
price of the bond = 1000 - 150 - (1000/(1.05^40))
= $707.9543177
coupon*(1 -(1/(1.05^40)))/0.05 = 707.9543177
coupon*17.15908635 = 707.9543177
coupon = 41.25827583
coupon rate = 8.25%
Therefore, coupon interest rate that the company must set on the bonds in order to sell the bonds-with-warrants at par is 8.25%.
