Q: John decides to get a new phone number and it ends up being a recycled number. He used to get 20 text messages a day. Now he is getting 55. Assuming the number of texts his friends send has not changed, how many text messages per week is he getting that are not intended for him?
A: He is getting an extra 55 - 20 = 35 text messages per day. So he is getting an extra 35 * 7 = 245 text messages per week. The answer is 245.

Q: A pen and pencil have a total cost of $6. If the pen costs twice as much as the pencil, what is the cost of the pen?
A: Let x be the cost of the pencil. If the pen costs 2 times the cost of the pencil, then it costs 2x. Adding the cost of the pen and pencil we get 2x + x = 3x. Since the total cost is $6 then 3x = $6 therefore x = $6 / 3 = $2. One pen is equal to 2 * x which is 2 * $2 = $4. The answer is 4.

Q: John eats 3 meals a day. Breakfast is 500 calories. His lunch contains 25% more calories than that. His dinner is twice as many calories as lunch. He also has 3 shakes that are each 300 calories. How many calories does he get in a day?
A:
Lunch is 500 * .25 = 125 more calories than breakfast. That means it is 500 + 125 = 625 calories. So dinner is 625 * 2 = 1250 calories. The shakes are 3 * 300 = 900 calories. So in total he eats 500 + 625 + 1250 + 900 = 3275 calories. The answer is 3275.
