The expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54

<h3>How to determine the expression?</h3>

Let the number of students in 2010 be s.

So, we have:

Year 2011 = 1/2s i.e. half as many students in 2010
Year 2012 = s - 54 i.e. 54 students less than 2010

The total number of students is:

Total = s + 1/2s + s - 54

Evaluate

Total = 9s/2 - 54

Rewrite s:

Total = 5.5s - 54

Hence, the expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54
