The model chooses a correct method but executes it wrongly (or vice versa) — a right-approach/wrong-answer or wrong-approach/right-answer split. The rule
A shop sells 17 boxes holding 24 items each, then 8 items are returned. How many items were sold?
First, calculate the total number of items in the boxes: Total items = Number of boxes × Items per box Total items = 17 boxes × 24 items/box = 408 items Next, account for the 8 items that were returned: Items sold = Total items - Returned items Items sold = 408 items - 8 items = 400 items Answer: 400

To find out how many items were sold, we first calculate the total number of items in the boxes and then subtract the number of items returned. 1. Calculate the total number of items in the boxes: \[ \text{Total items} = \text{Number of boxes} \times \text{Items per box} = 17 \times 24 = 408 \] 2. Subtract the number of items returned: \[ \text{Items sold} = \text{Total items} - \text{Items returned} = 408 - 8 = 400 \] Thus, the number of items sold is 400. Answer: 400

400. Order matters: multiply before subtracting.

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.
