conversations.value: I need a clearer understanding of how to solve: Robert wants to buy a bookshelf and a sofa and has received two offers. Furniture United's offer includes a $1,350 advance payment and 6 monthly installments of $350 each. Cozy Homes' offer includes a $1,100 advance payment and 9 monthly installments of $250 each. What is the cost difference between the two offers?

conversations.value: Furniture United's offer is 1,350 + (6 *350) = $3,450
  Cozy Homes's offer is 1,100 + (9 * 250) = $3,350
  The difference is 3,450 – 3,350 = $100
