[Question]The pizza delivery person has 12 pizzas to deliver. If two of the stops are for orders of two pizzas and the rest are for single pizzas, how many minutes per stop does the delivery person need to average to deliver all of the pizzas in 40 minutes?
[Answer]If two pizzas will be delivered at two of the stops, the total number of stops will be 12 - 2 = 10 stops. If there are 10 stops in 40 minutes, then the delivery person needs to average 40 / 10 = 4 minutes per stop. The answer is 4.

[Question]Luca went to a sandwich shop for lunch. The sandwich he bought was normally $8, but he had a coupon for a quarter of the price off. He then upgraded it with sliced avocado for an extra dollar. After adding a drink and a $3 salad, his total lunch bill was $12. How many dollars did Luca pay for his drink?
[Answer]Luca’s coupon saved him 8 / 4 = $2 on his sandwich. He paid $1 for avocado on his sandwich, so the sandwich cost 8 - 2 + 1 = $7. He paid $3 for his salad, so his meal without the drink was 7 + 3 = $10. Thus, Luca paid 12 - 10 = $2 for his drink. The answer is 2.
[Question]A row of houses all share a community space where they put up their clotheslines. There are 2 clotheslines for every house on the street. On the street, there are a total of 11 children and 20 adults. Each child currently has 4 items of clothing on the clotheslines and each adult currently has 3 items of clothing on the clotheslines. If each clothesline can hold 2 items of clothing and all of the clotheslines are full, how many houses are on the street?
[Answer]
From the children, there are a total of 11 children * 4 items of clothing each = 44 items of clothing on the clotheslines. From the adults, there are a total of 20 adults * 3 items of clothing each = 60 items of clothing on the clotheslines. So there are a total of 44 + 60 = 104 items of clothing on the clotheslines. This means that there are 104 items of clothing / 2 items of clothing per clothesline = 52 clotheslines. There are 2 clotheslines per house so there must be 52 clotheslines / 2 = 26 houses on the street. The answer is 26.
