Answer:
(B) 9%
Explanation:
In order to calculate this you just have to do a simple rule of three with the 100% being the 450,000 you withdraw from the paid money the selling price of the bonds:
490,222-450000= 40,222
Now we do the rule of three using 450,000 as 100%:
[tex]\frac{450,000}{100}=\frac{40,222}{x} \\x=\frac{40,222*100}{450,000}\\ x=8,93 %\\[/tex]
So the actual rate would be 8,93 which is closest to 9% so that would be the answer.
