Given:
Apples she first picked = w
Additional apples she picked = r
Number of apples she fed to the horses = 2
Let's find the expression that represents the total number of apples she has at the end of the day.
Since she picked w apples, them an additional r apples, add both terms together:
w + r
She then fed 2 apples to the horses, subtract 2 from the sum of apples picked.
Thus, we have:
w + r - 2
Therefore, the total number of apples she has at the end of the day
