Explanation:
To get the total amount of sandwiches sold in the first week, we would need to add up all of the ham, tuna, and cheese sandwiches.
32 + 46 + 18 = 96
The shop sold 96 sandwiches in the first week.
To find out how many more sandwiches the store sold in the second week, we will need to add up all of the sandwiches again.
38 + 43 + 24 = 105
The shop sold 105 sandwiches in the second week.
Taking 105, we can subtract 96 from it to get how many more sandwiches the shop sold in week 2.
105 - 96 = 9
The shop sold 9 more sandwiches in the second week.
