A pencil with an eraser, which costs $0.8 each, a regular pencil for $0.5 each, and a short pencil for $0.4 each. This store was able to sell 200 pencils with an eraser, 40 regular pencils, and 35 short pencils. How much money did the store make from these sales?

conversations.value: For pencils with erasers, the store received a total of 200 * 0.8 = $160.
  For regular pencils, the store received 40 * 0.5 = $20.
  And for short pencils only 35 * 0.4 = $14.
  In total, the store made 160 + 20 + 14 = $194 from selling these pencils.
