A grocery store tracks the number of items sold per day by a vendor. A new vendor transfers to the store with 300 items already sold and sells an average of 25 items per day. The linear function v(x) = 25x + 300 models the vendor's sales, where x is the number of days and v(x) is the total number of items sold.
Part A: How many items will the vendor have sold after 10 days? Show all necessary steps. (2 points)
Part B: If the vendor must leave the store after 20 days, how does that change the domain and range of the given function v(x)? (2 points)
