When the bonds will mature, the company will receive, maturity value plus the interest earned on the bonds.
The maturity value will be the par value, as nothing is given, the bonds are redeemed at par value i.e. $ 46,000.
The interest income will be calculated as -
Interest Income = 7 % * $ 46,000 = $ 3,220
Thus, the total cash proceeds = $ 46,000 + $ 3,220 = $ 49,220
