Chever Portal Tor put 3 bags of balls in the gym locker. Each bag had 7 balls. Then Tor found 2 more balls in the gym and put them in the locker. complete the equation to show how to find \( b \), the number of balls Tor put away. 2

To find \( b \), the equation can be set up as follows: \( b = 3 \times 7 + 2 \). This means Tor put away the total number of balls by first calculating the total from the 3 bags (which is 21 balls) and then adding the 2 extra balls he found. So, \( b = 21 + 2 \), leading to \( b = 23 \). To ensure this equation makes sense, let’s break it down: the first part reflects the multiplication of bags by balls per bag, and the second part adds the additional found balls. This framework helps organize thoughts when tackling similar problems involving collections.
