[Question]: Lauren sent 65 pieces of mail on Monday, 10 more pieces of mail on Tuesday than on Monday, 5 fewer on Wednesday than on Tuesday, and 15 more pieces of mail on Thursday than on Wednesday. How many pieces of mail did Lauren send?
[Answer]: Lauren sent 65 + 10 = 75 pieces of mail on Tuesday. He sent 75 - 5 = 70 pieces of mail on Wednesday. And sent 70 + 15 = 85 pieces of mail on Thursday. Therefore, he sent 65 + 75 + 70 + 85 = 295 pieces of mail.
So the answer is 295.

[Question]: 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?
[Answer]: 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.
So the answer is 39.

[Question]: Stan weighs 5 more pounds than Steve. Steve is eight pounds lighter than Jim. If Jim weighs 110 pounds and the three of them crowd onto a scale at the same time, what is their total weight?
[Answer]:
Steve weighs 110 - 8 = 102 pounds. Stan weighs 102 + 5 = 107 pounds. Their total weight is 102 + 107 + 110 = 319 pounds.
So the answer is 319.
