Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
The order for the two children costs 10 dollars for each pizza, and 1 dollar per topping.  Each child gets 1/2 a pizza.  So the cost for the two children is 10 dollars for each pizza, plus 1 dollar per topping per child, or (10+2) dollars per pizza, or (10+2)*2 = <<(10+2)*2=24>>24 dollars.
Ruby and her husband get 1/2 a pizza, so their order costs 10 dollars plus 1 dollar per topping, or (10+2) dollars, or 10+2 = <<10+2=12>>12 dollars.
The total cost, including the tip, is 24+12+5 = <<24+12+5=41>>41 dollars.
