Step-by-step reasoning process: On days one, two, and three he sold 5 cars each day so, 5 cars + 5 cars + 5 cars = 15 cars that he sold on those days. On days 4,5,6 and 7 he sold 3 cars each day so, 3 cars + 3 cars + 3 cars + 3 cars = 12 cars that he sold on those days. Now we combine the cars he has already sold, which is 15 cars, and 12 cars, so 15 cars + 12 cars = 27 cars are sold in total. If he needs to sell 50 cars and has already sold 27 cars then 50 cars - 27 cars = 23 cars left to sell to meet his quota.

Step-by-step reasoning process: Her card has a $150.00 balance and she makes a $50.00 payment so the new balance is 150 - 50 = $100.00. She didn't pay it off so she is charged 20% interest on her $100.00 balance so the interest is .20 * 100 = $20.00. Her balance was $100.00 and she was charged $20.00 in interest so her new balance is 100 + 20 = $120.00.
