Question: There are 10 cars parked in a mall’s parking lot, each with the same number of customers inside. Each customer only makes 1 purchase. If the sports store makes 20 sales and the music store makes 30 sales, how many customers are in each of the cars?
Answer: As each sale represents a customer, there must be a total of 20 sports store sales + 30 music store sales = 50 customers. There is an equal number of customers in every car, so there must be 50 total customers / 10 cars = 5 customers in each car. The answer is 5.
[Question]Adam goes to school every day. On Monday he had 6 lessons of 30 minutes each, and on Tuesday he had 3 lessons of 1 hour each. On Wednesday, Adam spent twice as much time at school as on Tuesday. How much time in total did Adam spend at school during these 3 days, in hours?
