Question

There were s students at a summer camp in 2010. In 2011, there were half as many students as the previous year. In 2012, there were 54 fewer students than in 2010. What expression would represent the total number of students at the summer camp for all three years?
55s
Five-halves s minus 54
3s – 54
Five-halves s + 54

Answer 1

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

How to determine the expression?

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
