a-34%
b-32%
c-28%
d-30%

The answer is 30%.

Step-by-step explanation:

Keena Williams took out a $100,000, 5-year term policy at age 40.

The premium per $1,000 was $3.56, so total premium is

= $356

She will be 45 years old this year.

The premium per $1,000 will be $4.62, so total premium will be $462

Premium that increased =

So, the percentage increase will be =

Rounding to nearest whole number, we get 30%.

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
