conversations.value: Please show me the solution for: Ruby was going to order pizza for dinner.  Her son would only eat pepperoni pizza.  Her daughter would only eat sausage.  Ruby and her husband wanted black olive and mushroom pizza.  To make life easy, Ruby decided to order an entire pizza for each of her children and she would split one with her husband.  The pizza restaurant charged $10.00 per pizza and $1.00 per topping.  She also needed to add a $5.00 tip.  Including tip, how much would the pizza order cost?

conversations.value: Ruby was going to order 1 for her son, 1 for her daughter and 1 to share with her husband. So she needed to order 1+1+1 = 3 pizzas
  Each pizza cost $10 and she was ordering 3 so that comes to 10*3 = $30.00
  She needed to order pepperoni, sausage, black olive and mushroom, which came to 4 toppings at $1.00 each so 4*1 = $4.00 extra for toppings
  The pizzas cost $30 and $4 for the toppings so the total costs of the pizzas came to 30+4 = $34.00
  She also had to add a $5.00 tip to her current order total of $34.00 so 5+34.00 = $39.00 for the total order
