I believe that the answer is D) whole-life
it usually covers up to 95
N = 13/20 or 0.65
25.5n - 3 = 5.5n + 10
Add 3 to both sides of the equation.
25.5n = 5.5n + 13
Subtract 5.5n from both sides.
20n = 13
Divide both sides by 20.
n = 13/20 or 0.65
the answer is 8.962790 because it is rounded to the nearest millionth
I hope this helps you
