Final answer:
Without the cost in tickets for each item, it's impossible to determine the total tickets used by Inez. A calculation would involve multiplying the ticket cost per item by the quantity and summing the totals.
Step-by-step explanation:
The question provided does not contain sufficient information to determine exactly how many tickets Inez used for the rings and stickers because we are not told the ticket cost of each item. However, I can give you a big explanation part about how to approach this problem if we were to know the ticket cost per item. If we knew how many tickets each ring and sticker cost, we would simply multiply the number of rings by their ticket cost and do the same for the stickers, then add the two amounts together to find the total number of tickets Inez used.
