She simplified it wrong because you're only supposed to simplify it with the same numbers. For example: simplify 2/4. You divide it by 2/2. You do the same and it will be correct.
Answer:
AC ≈ 2.18
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan70° =
=
= 
Multiply both sides by AC
AC × tan70° = 6 ( divide both sides by tan70° )
AC =
≈ 2.18 ( to the nearest hundredth )
7844=7400(1+(8/12)r)
Solve for r
R=0.09*100=9%
