To find the total number of rings, calculate the rings in the boxes with 3 rings each and the boxes with 4 rings each, then add the totals to find the overall number of rings.
To find the total number of rings, first calculate the rings in the 5 boxes with 3 rings each: 5 boxes 3 rings/box = 15 rings. Next, calculate the number of boxes with 4 rings each, which is the double of the previous set, so 2 5 = 10 boxes. Multiply the number of boxes with 4 rings by the number of rings per box: 10 boxes * 4 rings/box = 40 rings. Add the rings from both sets to get the total: 15 rings + 40 rings = 55 rings in total.
