Answer:
5. The answer is 2
6. Her error is that she was supposed to subtract 16 minus 12 instead of 12 minus 2.
Step-by-step explanation:
For number 5 all I did was solve.
12 + (25 - 5^2) - 2 =
12 + 0 - 2 =
12 - 2 = 10
10 ÷ 5 = 2
So, for number 5 the answer is 2.
For number 6, you should know that when there are only plus and minus signs you solve from left to right.
She instead put parentheses where there shouldn't of been, and because of that she is wrong.
Hope this helps! :)

The selling price would be $420.
Step-by-step explanation:
In order to find the mark up, we need to multiply the amount it originally costs by the percentage it is being marked up.
$300 * 40% = $120
Now that we have the mark up amount, we add it to the original cost to get the sale price.
$300 + $120 = $420
