Which expression represents the total number of apples eaten by these students in one week

The answer is the last option. 2x + (x + 3x).

Step-by-step explanation:

First, you start with PEMDAS. The first one is brackets or parenthesis. It says that x = 1 apple. So 3 multiplied by 1 is 3. the answer is 3. next to it is an "x" which, again represents 1 apple. So 3 + 1 = 4

Now the equation looks like this:

2x + 4

Since x is the variable that represents 1 apple, you multiply 2 and 1. The answer is 2.

Now your equation should look like this:

2 + 3 = ?

The answer is 6. And in the chart/table, it displays 6 apples in total.
