Answer 2

`80\leq x\leq 70`

Explanation:

Mr. Venn knows that 60% of his students will score no more than 5 points above or below the class average, 75%, on the test.

Means the greater marks can be up to 80 and lowest marks can be up to 70.

So, the inequality that represents the test scores of 60% of his students is :

`80\leq x\leq 70`
