- The mean of the data set is 35 apples.
- Let's call
the number of apples.
The means is defined as the quotient between the sum of all elements and the total number.
Mathematically, it would be defined as

But, we know that the mean is equal to 35.

Then, we solve for 

As you can see, the total number of apples depends on the sum of all elements of the data set.
For example, if the sum of all elements is 700, the total number of apples would be

Therefore, the expression that represents the total number of apples is
