conversations.value: To raise funds for her local soup kitchen, Didi enlisted the help of her family, friends, and neighbors. They donated 10 same-size cakes that she sliced into 8 slices per cake and started selling a slice for $1. A local business owner was so impressed by Didi's efforts that she offered to donate 50 cents for each slice Didi sold. A second business owner also offered to donate a quarter for each slice sold. If Didi sold all the slices, how much money did she raise?
  Find the solution.

conversations.value: All the cakes yielded 10 * 8 = 80 slices
  Since Didi was selling each slice for $1, it means she sold everything for 80 * 1 = 80 dollars.
  The first business owner donated 50/100 * 80 = 40 dollars.
  The second business owner donated 25/100*80= 20 dollars
  Adding both amounts gives 80 + 40 + 20 = 140 dollars
