Which expression gives the same result as ∑4i=0(5)(1/3)i

I'm assuming which expression gives the same result as ∑^4
The choices are:
i=0^(5)
(1/3)^i

The second option is correct since the first option is erroneous or makes little sense. The second option and the ∑^4 are geometric progressions which will account for each other when substituted together or one into another. 

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
