**Mariella.**, Wednesday, November 2, 2011 at 9:09pmHow many cars were there altogether?

**Mandy**, Wednesday, November 2, 2011 at 9:13pmIt doesn't say how many cars in total there were. Im guessing that in total these cars added up to 100%.

b.)1/4

**Mandy**, Wednesday, November 2, 2011 at 9:19pmIs there anyway that you can show me how you got that so I can understand a little better? Thanks!

**Mariella.**, Wednesday, November 2, 2011 at 9:22pma.)40% of cars are either brown or green. Divide that by two since there are two colors. You get 20. Put that over 100=20/100. Reduce it to 2/10 which reduces to 1/5.

b.)Add all the percents together to get 80%. Subtract it from 100. 100-80=20. 20/100=1/5. So the actual answer to b is 1/5. Sorry, my mistake. :P

**PsyDAG**, Wednesday, November 2, 2011 at 10:22pmWhat about the undefined remaining 20%?

30% + 40% + 10% = only 80%
