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?

Answer 1

The expression that represents the total number of students at the summer camp for three years is (3/2)s - 54.

Step-by-step explanation:

To represent the total number of students at the summer camp for all three years, we need to add up the number of students in each year. Let's break it down:

In 2010, there were s students.

In 2011, there were half as many students as the previous year, so the number of students would be s/2.

In 2012, there were 54 fewer students than in 2010, so the number of students would be s-54.

To represent the total number of students, we add these three expressions together: s + s/2 + s-54. This can also be simplified to (3/2)s - 54.
