conversations.value: Julie wants to give her favorite cousin a $2345 mountain bike for his birthday. So far, she has saved $1500. Since the birthday is still a few weeks away, Julie has time to save even more. She plans on mowing 20 lawns, delivering 600 newspapers, and walking 24 of her neighbors’ dogs. She is paid $20 for each lawn, 40 cents per newspaper, and $15 per dog. After purchasing the bike, how much money will Julie have left?
  Work out the solution step by step.

conversations.value: Mowing lawns will earn Julie 20*20 = 400 dollars
  Her earnings, in dollars, from delivering newspapers will be 600 *40/100 = 240 dollars
  After walking 24 of her neighbor’s dogs, she will earn 24* 15 = 360 dollars.
  She will therefore earn a total of 400 + 240 + 360 = 1000 dollars
  Combining earnings from her job with her savings will give Julie 1000 + 1500 = 2500 dollars
  Subtracting the cost of the mountain bike from the total will leave Julie with a balance of 2500 - 2345 = 155 dollars
