Calculate Remainder: 35 Rings in a 2×10 Jewelry Box

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Calculate the total capacity of the jewelry box
• Step 3: Determine how many rings will be left out

Now, let's work through each step:

Step 1: The problem gives us 35 rings. The jewelry box has 2 rows, and each row can hold 10 rings.

Step 2: We'll calculate the total capacity of the jewelry box:

The capacity of one row is $10$ rings. Since there are 2 rows, the total capacity is $2 \times 10 = 20$ rings.

Step 3: To find out how many rings will be left out after filling the box, subtract the box's total capacity from the total number of rings:

$35 - 20 = 15$

Therefore, the number of rings that will be left out is $15$.
