Sara discarded 1/10 of apples she picked as defective. Of the apples remaining, 300 we're made into cider. The rest were sold as fresh fruit. What is the total apples picked were sold as fresh fruit?

Let x be the total number of picked apples.

Sara discarded x/10 apples.
The number of apples remaining is x - x/10 = 9x/10.
Out of these, 300 apples we're made into cider, so the number of apples remaining after being made into cider is 9x/10 - 300.
These apples were sold as fresh fruit, so 9x/10 - 300 were sold as fresh fruit.
Therefore, the total number of apples sold as fresh fruit is 9x/10 - 300. Answer: \boxed{ \frac{9x}{10} - 300}.

To find the total number of apples Sara sold as fresh fruit, we need to know the amount of apples she picked initially. However, this information is not given in the question.

To find the total number of apples that were sold as fresh fruit, we need to calculate the apples remaining after Sara discarded 1/10 of the picked apples and then subtract the 300 apples that were made into cider.

Let's break down the process step by step:

Step 1: Calculate the number of apples Sara picked (before discarding).
Assume the total number of apples Sara picked is 'x'.

Step 2: Calculate the number of apples Sara discarded as defective.
As stated in the problem, Sara discarded 1/10 of the apples she picked.
So, the number of apples discarded can be calculated as (1/10) * x.

Step 3: Calculate the number of apples remaining after discarding.
The number of apples remaining can be calculated as x - (1/10) * x.
Simplifying this equation, we get 9/10 * x.

Step 4: Subtract the apples used for making cider.
Out of the remaining apples, 300 were used for making cider.
So, the number of apples left for sale as fresh fruit is (9/10 * x) - 300.

Therefore, the total number of apples that were sold as fresh fruit is (9/10 * x) - 300.
