Using a savings interest calculator, I found that either way your savings grow by exactly $1,020.20, so they share the same interest.
Given:
Planes X and Y are perpendicular to each other
Points A, E, F, and G are points only in plane X
Points R and S are points in both planes X and Y
Lines EA and FG are parallel
The lines which could be perpendicular to RS are EA and FG.

Put 163 on top and then 66 on bottoms of the equation and then subtract. 3-6 u can't do so u barrow from the 6 and turn the 6 into a 5 and the 3 into a 13 then subtract 13 from 6 and get 7 then u can't subtract 5 from 6 so barrow from the 1 to make the 5 a 15 and the 1 to a 0 and then subtract 15 from 6 and get 9 and ur answer is 97!
