ANSWER
m < -2
EXPLANATION
We want to find the solution set for m in:
![-3m+1>7](https://tex.z-dn.net/?f=-3m%2B1%3E7)
First, collect like terms:
![\begin{gathered} -3m>7-1 \\ -3m>6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-3m%3E7-1%20%5C%5C%20-3m%3E6%20%5Cend%7Bgathered%7D)
Now, divide both sides by -3. When you divide an inequality by a negative number, <em>the sign changes direction</em>:
![\begin{gathered} \frac{-3m}{-3}>\frac{6}{-3} \\ m](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B-3m%7D%7B-3%7D%3E%5Cfrac%7B6%7D%7B-3%7D%20%5C%5C%20m%3C-2%20%5Cend%7Bgathered%7D)
This means that all values of m must be less than -2.
<em>None of the options contains the correct solution set.</em>

Step-by-step explanation:
I was doing it wrong. You have to find 30% of $86 which is $25.80, i think, and then take it away from $86 and so the sales price is $86 - $25.80 = $60.20. Originally I only did the first bit, I forgot you have to take it away. sorry hope this helps more now.
