Question: Danny made chocolate cookies for his class and made sure each cookie had exactly 7 chips. He made 4 dozen in total. If the class eats half the cookies, how many chips are left uneaten?
Answer: There are 48 cookies because 12 x 4 = 48. There are 24 cookies left because 48 / 2 = 24. There are 168 chips left because 24 x 7 = 168. The answer is 168.

Question: Ron ate pizza with his friends the other day. If they ordered a 12-slice pizza and each of them ate 4 slices, how many friends were there with Ron?
Answer: Let the number of friends that ate with Ron be represented by F. That means the total amount of people that ate that day were 1 + F. If each of them ate 4 slices, and the pizza only has 12 slices, that means there could only have been 12 / 4 = 3 people eating. If the total number of people eating was 3, and if was also represented by 1 + F then we have 3 = 1 + F. Solving for F we have 3 - 1 = F. F = 2 friends ate with Ron. The answer is 2.

Question: Suzie and 5 of her friends decide to rent an Airbnb at Lake Tahoe for 4 days from Thursday to Sunday. The rental rate for weekdays is $420 per day. The weekend rental rate is $540 per day. They all decide to split the rental evenly. How much does each person have to pay?
Answer:
The cost of the rental for Thursday and Friday comes to $420 * 2 = $840. The cost of the rental for Saturday and Sunday comes to $540 * 2 = $1080. The total cost of the rental comes to $840 + 1080 = $1920. The payment required for each person comes to $1920 / 6 = $320. The answer is 320.
