Hello there! The cost of the item is $40, which makes up 100% of the price. There is 8% tax applied on the item. Let's add both percentages. 100 + 8 is 108. That's 108%. Let's multiply that by 40 to get the total price. 40 * 108% (1.08) is 43.2. There. The final cost of an item is $43.20.

Step-by-step explanation:
3 (4 -6) = -8 is correct.  The next step is to combine 4 and -6, obtaining
3(-2)
and this 3(-2) should equal -6, which is not the same as -8.
3(4 - 6) = 12 - 18, which differs from the student's solution.  This is the reason for the wrong answer.
