Reina has three times the number of counters and four times the number of marbles as Kevin. If Kevin has 40 counters and 50 marbles, calculate the number of counters and marbles that Reina has? Let's be accurate as possible.
If Kevin has 40 counters, and Reina has three, the number of counters Kevin has, Reina has 3 * 40 = 120 counters. Reina also has four times the number of marbles that Kevin has, meaning he has 4 * 50 = 200 marbles. In total, Reina has 120 counters + 200 marbles = 320 items.
The answer: 320.
