If Kevin has 40 counters, and Reina has three, the number of counters Kevin has, Reina has 3*40 = <<40*3=120>>120 counters.
Reina also has four times the number of marbles that Kevin has, meaning he has 4*50 = <<4*50=200>>200 marbles.
In total, Reina has 120 counters + 200 marbles = <<120+200=320>>320 items.
