Lizzy: Belinda's dog is missing, so she made 200 flyers to distribute around town with the help of her friends. Ryan passed out 42 flyers, Alyssa passed out 67, Scott passed out 51 and Belinda passed out the rest. What percentage of the flyers did Belinda pass out?.
Me: Hmmm, let me think. I think this is the detailed solution:
The total number of flyers Belinda's friends passed out was 42 by Ryan + 67 by Alyssa + 51 by Scott = 160 flyers. Belinda passed out 200 total flyers 160 flyers passed out by friends = 40 flyers. To express this as a decimal, divide Belinda's 40 flyers / 200 total flyers = 0.20. Belinda passed out 0.20 x 100% = 20% of the flyers. Final answer: 20.
