Consider the given parallelogram KLMN.
Prove:
Statement Reason
1. Definition of parallelogram
2. Same Side interior angle theorem
3. Substitution property
4. Subtraction property of equality
Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
5. Angle Congruence Postulate
When two angles are equal, then they are said to be congruent by Angle congruence postulate.
Is the question - did they mistakenly say "dollar" rather than "years?"
x = # of years
10,000 = 20,000 (0.85)^x, first divide both sides by 20,000
0.5 = (0.85)^x, next take the ln of both sides
ln 0.5 = ln (0.85)^x, by rules of logarithms you may move x to make it a coefficient of the logarithm
ln 0.5 = x (ln 0.85), divide both sides by ln (0.85)
x = (ln 0.5)/ (ln 0.85) = (-0.693)/(-0.1625) = 4.26 years
