conversations.value: It’s spring! The gardener at Parc Municipal orders flowers. He takes 250 tulips, 375 carnations and 320 roses. Each flower is sold for 2€. Calculate the total expenses.
  Give me a clear explanation.

conversations.value: First we calculate the number of flowers: 250 + 375 + 320 = 945€
  Then the expense: 945 X 2 = 1890€
  So, the total expenditure is €1890.
