conversations.value: Can you break down the solution for me for this math problem: Moore's family compared mobile phone plans to get the best deal. At T-Mobile, the family plan costs $50 per month for the first two lines and $16 for each additional line. At M-Mobile, the family plan costs $45 for the first two lines and $14 for each additional line. Moore's family needs to purchase 5 cell phone lines. How much cheaper is the M-Mobile than T-Mobile?

conversations.value: The three additional lines at T-Mobile cost $16 x 3 = $48.
  The total cost of the family plan at T-Mobile is $50 + $48 = $98.
  The three additional lines at M-Mobile cost $14 x 3 = $42.
  The total cost of the family plan at M-Mobile is$45 + $ 42 = $87.
  Therefore, M-Mobile is $98 - 87 = $11 cheaper than T-Mobile.
