A company is analyzing its sales trends over the past few months. They found that in January, the sales totaled $2,000, and in February, the sales increased by $150 per month. If the sales in March can be represented by the linear equation $y = 150x + 2000$, where $x$ is the number of months after January, what will be the total sales in March? Additionally, if the sales in April are expected to increase by $200 from March's sales, what will be the total sales in April? Let's think step by step and output the final answer within \boxed{}.
