Problem Solving: Finding the Initial Number of Red Apples

To solve this problem, we can use the information provided and work backwards to find the initial number of red apples in the basket.

Given: - Initially, there were some red apples in the basket. - 15 green apples were added to the basket. - After half of all the apples were taken from the basket, 18 apples remained.

Let's denote the initial number of red apples as R.

Calculating the Initial Number of Red Apples

1. Total Number of Apples: Initially, there were R red apples, and 15 green apples were added, so the total number of apples became R + 15. 2. Half of the Apples: After taking half of all the apples, there were 18 apples left. This means that the total number of apples was twice the number left, so the total number of apples initially was 2 * 18 = 36. 3. Equation: We can now set up an equation to solve for R: - R + 15 = 36 - R = 36 - 15 - R = 21

Answer

The initial number of red apples in the basket was 21.
