Exercise
Answer
Answer: B
There is no change to [math]{ }_{9} V[/math] because there were no errors after time 9 .
An equation for [math]{ }_{8} V^{\text {orig }}[/math] is [math]{ }_{8} V^{\text {orig }}+P-e=1000(0.003736) / 1.05+100(0.996264) / 1.05[/math]
An equation for [math]8 V^{\text {now }}[/math] is [math]8 V^{\text {now }}+P-e=1000(0.002736) / 1.05+100(0.997264) / 1.05[/math]
By subtraction, [math]{ }_{8} V^{\text {now }}-{ }_{8} V^{\text {orig }}=1000(-0.001) / 1.05+100(0.001) / 1.05=-0.86[/math]
[math]{ }_{8} V^{\text {now }}=86.74-0.86=85.88(\mathrm{~B})[/math]
In those equations, [math]P-e[/math], which cancels, represents the gross premium less all expenses. You could think of [math]P[/math] as the gross premium less commissions, and e as the flat expenses. However you think of representing them, they cancel.
