To find the current price of milk after the changes, we start with the initial price of $2.65.
1. The price rises by \( y \) dollars:
\[
2.65 + y
\]
2. The price then drops by $0.15:
\[
(2.65 + y) - 0.15 = 2.50 + y
\]
3. Finally, the price rises again by $0.05:
\[
(2.50 + y) + 0.05 = 2.55 + y
\]
Thus, the current price of milk can be expressed as:
\[
2.55 + y
\]
Therefore, the correct option is **2.55 + y**.
1. The price rises by \( y \) dollars:
\[
2.65 + y
\]
2. The price then drops by $0.15:
\[
(2.65 + y) - 0.15 = 2.50 + y
\]
3. Finally, the price rises again by $0.05:
\[
(2.50 + y) + 0.05 = 2.55 + y
\]
Thus, the current price of milk can be expressed as:
\[
2.55 + y
\]
Therefore, the correct option is **2.55 + y**.
