conversations.value: Please show me the solution for: Ford owns a garden and he grows 40 roses every week. He supplies Roses to the local flower shops. The first flower shop orders 20 roses, the second flower shop orders 15 roses, and the third flower shop orders 30 roses per week. How many roses does Ford lack to supply all the flower shops every month?
conversations.from: assistant
conversations.value: The first flower shop needs 20 x 4 = 80 roses every month.
  The second flower shop needs 15 x 4= 60 roses every month.
  The third flower shop needs 30 x 4 = 120 roses every month.
  So the total number of roses that all the flower shop needs every month is 120 + 80 + 60 = 260.
  The total roses Ford grows every month is 40 x 4 = 160
  Therefore, the total number of roses he lacks is 260 - 160 = 100 to supply all the flower shops every month.
