A beekeeper’s initial observation of the population of a certain bee colony was 1,600 bees. The beekeeper set a goal to increase the population to 2,975 bees. The beekeeper uses a model that predicts the population of this bee colony begins at 1,600 and increases by 110 bees per week in the first two weeks after the initial observation, and then increases by 165 bees per week until the beekeeper’s goal is reached. According to this model, at the end of week \( w \) after the initial observation, where \( w>2 \), which of the following functions gives the predicted number of bees still needed to reach the beekeeper’s goal?
