How to figure out Percentage?

Question

there are 35 buses at a station. 80 % are long distance buses. if 50 % of the long-distance buses left the station, what will be the new percentage of long-distance buses at the station? Round to nearest tenth of a percent.

so, i think I have it part of the way.... I got 28 are Long-distance buses (35 *.80)

then 50 % of those is 24...so 24 left the station. Assuming I am correct thus far, I can't for the life of me get the rest it seems.

Please Help

Answer 1

So, let's start by saying that the most important part of my pencil is the eraser!

 

50% of 28 is 24? You know it's 14! That leaves 14 long distance buses and a total of 21 busses at the station.

 

14/21 = 0.6666... = 66.7%
