A shop sells 17 boxes holding 24 items each, then 8 items are returned. How many items were sold?
To solve this problem, we need to find the total number of items sold and then subtract the number of items returned. Given information: - The shop sells 17 boxes, each holding 24 items. - 8 items are returned. Step 1: Calculate the total number of items sold. Total items sold = Number of boxes × Number of items per box Total items sold = 17 × 24 = 408 items Step 2: Subtract the number of items returned. Total items sold - Items returned = Final number of items sold Final number of items sold = 408 - 8 = 400 items Answer: 400 items

To solve this problem, we need to calculate the total number of items sold, taking into account the returned items. Given information: - The shop sells 17 boxes, each holding 24 items. - 8 items are returned. Step 1: Calculate the total number of items sold. Total items sold = Number of boxes × Number of items per box Total items sold = 17 × 24 = 408 items Step 2: Subtract the returned items from the total items sold. Total items sold - Returned items = Final number of items sold Final number of items sold = 408 - 8 = 400 items Answer: 400 items were sold.

Unchanged by context: 0% with none, 0% with the strongest supplied source. For a control mode that flat line is the result — it is what licenses reading movement elsewhere in this loop as grounding rather than as a document being present. Nothing survives at the best condition on the cases measured here.
