Question: A desert garden’s sprinkler system runs twice a day during the cool morning and evening hours. It waters the garden with four liters of water in the morning and six liters in the evening. How many days does it take the sprinkler system to use 50 liters of water?
Answer with step-by-step thinking: Every day, the sprinkler uses 4 + 6 = 10 liters of water. Hence, it takes the sprinkler system 50 / 10 = 5 days to use 50 liters of water.

Question: Jimmy is a pizza delivery man. Each pizza costs 12 dollars and the delivery charge is 2 extra dollars if the area is farther than 1 km from the pizzeria. Jimmy delivers 3 pizzas in the park, which is located 100 meters away from the pizzeria. Also, he delivers 2 pizzas in a building 2 km away from the pizzeria. How much money did Jimmy get paid for the pizzas?
Answer with step-by-step thinking: Adding the pizzas delivered in the park and in the building, Jimmy delivered a total of 2 + 3 = 5 pizzas. The value of the 5 pizzas without delivery charge is 5 pizzas * $12 / pizza = $60. The cost of the delivery charge for two pizzas is 2 pizzas * $2 / pizza = $4. In total, Jimmy got paid $60 + $4 = $64 for the pizzas.
So the answer is 64.
