Q: Zach was a waiter in a fancy restaurant. His last table for the night was a party for 4 people. The mom ordered lobster for $25.50, the dad ordered steak for $35.00 their twin boys both ordered a cheeseburger and fries for $13.50 each. They started their meal with an appetizer that cost 8.50. Everyone also ordered a dessert that cost $6.00 each. They wanted to give a 20% tip for Zach on the bill. What did the final bill total come to?
A: The twins ordered a cheeseburger each so 2 * 13.50 = $27.00 for both cheeseburgers. Everyone ordered a dessert so 4 * 6 = $24.00 for dessert. When you add all the meals together they spent 25.50 + 35.00 + 27.00 + 8.50 + 24.00 = $120.00. Zach's tip was 20% so .20 * 120.00 = $24.00. When you add up the meals $120.00 and Zach's tip of $24.00 then the total cost is 120.00 + 24.00 = $144.00. The answer is 144.

[Question]Tommy's mother lets him ride his bike 2 blocks north of his block, 3 blocks east, 2 blocks west, and 2 blocks south. His friend's father lets his friend ride his bike 80 square blocks. How many times greater is the area his friend can ride in compared to Tommy?
[Answer]Tommy's area is 5 blocks wide because 3 + 2 = 5. His area is 4 blocks tall because 2 + 2 = 4. The total area is 20 square blocks because 5 x 4 = 20. His friend's area is 4 times bigger because 80 / 20 = 4. The answer is 4.
