answer:Here's the modified `BusinessReport` class that includes the new field for the total number of units sold, the updated `summary` method, and the new `calculateProfit` method: ``` public class BusinessReport { private String month; private double salesUsd; private double salesUsdMoM; private double salesUsdYoY; private int uniqueBuyers; private double uniqueBuyersMoM; private double uniqueBuyersYoY; private int totalTransactions; private double totalTransactionsMoM; private double totalTransactionsYoY; private double avgSale; private double avgSaleMoM; private double avgSaleYoY; private int totalUnitsSold; public BusinessReport(String month, double salesUsd, double salesUsdMoM, double salesUsdYoY, int uniqueBuyers, double uniqueBuyersMoM, double uniqueBuyersYoY, int totalTransactions, double totalTransactionsMoM, double totalTransactionsYoY, double avgSale, double avgSaleMoM, double avgSaleYoY, int totalUnitsSold) { this.month = month; this.salesUsd = salesUsd; this.salesUsdMoM = salesUsdMoM; this.salesUsdYoY = salesUsdYoY; this.uniqueBuyers = uniqueBuyers; this.uniqueBuyersMoM = uniqueBuyersMoM; this.uniqueBuyersYoY = uniqueBuyersYoY; this.totalTransactions = totalTransactions; this.totalTransactionsMoM = totalTransactionsMoM; this.totalTransactionsYoY = totalTransactionsYoY; this.avgSale = avgSale; this.avgSaleMoM = avgSaleMoM; this.avgSaleYoY = avgSaleYoY; this.totalUnitsSold = totalUnitsSold; } public String getMonth() { return month; } public double getSalesUsd() { return salesUsd; } public double getSalesUsdMoM() { return salesUsdMoM; } public double getSalesUsdYoY() { return salesUsdYoY; } public int getUniqueBuyers() { return uniqueBuyers; } public double getUniqueBuyersMoM() { return uniqueBuyersMoM; } public double getUniqueBuyersYoY() { return uniqueBuyersYoY; } public int getTotalTransactions() { return totalTransactions; } public double getTotalTransactionsMoM() { return totalTransactionsMoM; } public double getTotalTransactionsYoY() { return totalTransactionsYoY; } public double getAvgSale() { return avgSale; } public double getAvgSaleMoM() { return avgSaleMoM; } public double getAvgSaleYoY() { return avgSaleYoY; } public int getTotalUnitsSold() { return totalUnitsSold; } public String summary() { String summary = In + this.getMonth() + , we sold + this.getTotalUnitsSold() + units + and saw + String.format(%.2f, this.getSalesUsd()) + of sales + ( + String.format(%.1f, this.getSalesUsdMoM()) + % MoM; + String.format(%.1f, this.getSalesUsdYoY()) + % YoY) + across + this.getUniqueBuyers() + unique buyers. + The average number of units per transaction was + String.format(%.2f, this.getAvgSale()) + ( + String.format(%.1f, this.getAvgSaleMoM()) + % MoM; + String.format(%.1f, this.getAvgSaleYoY()) + % YoY).; return summary; } public double calculateProfit(double costPerUnit, double profitMargin) { return this.getTotalUnitsSold() * costPerUnit * profitMargin; } public static void main(String[] args) { BusinessReport report = new BusinessReport(November 2022, 2074764, -22.4, -91.8, 10023, -25.5, -84.5, 148440, -21.4, -88.5, 13.98, -1.3, -28.8, 12345); System.out.println(report.summary()); double profit = report.calculateProfit(2.5, 0.35); System.out.println(Total profit for the month: + String.format(%.2f, profit)); } } ``` I've added a new field `totalUnitsSold` to the class and modified the constructor accordingly. I've also updated the `summary` method to include the new field and display the average number of units per transaction. Lastly, I've added the new `calculateProfit` method that takes in the cost per unit and the profit margin as arguments, multiplies them with the total number of units sold, and returns the total profit for the given month.

answer:The task asks to produce a grammatically correct version of a given input stream of words, considering case, punctuation, stem-based, intra-word, and digit punctuation errors. We don't need to normalize years or complete sentence fragments. Now, let's solve the given instance: Input: ['everyone', 'for', today's, 'live', 'office', 'hours', 'were', 'joined', 'by', 'adora', 'and', 'Vito', 'and', I'll, 'leave', 'it', 'to', 'them', 'to', 'introduce', 'themselves', 'I', 'am', 'a', 'partner', 'at', 'Y', 'Combinator', 'previously', 'I', 'had', 'a', 'was', 'a', 'founder', 'CEO', 'of', 'a', 'startup', 'called', 'homejoy', 'say', 'a', 'virtual', 'guard', I'm, 'going', 'to', 'call', 'like', 'three', 'expert', 'I', 'was', 'most', 'definitely', 'director', 'of', 'product', 'at', 'Facebook', 'done', 'a', 'couple', 'startups', 'sold', 'a', 'couple', 'in', 'less', 'than', 'a', 'bunch', 'load', 'already', 'nice', 'to', 'meet', 'you', 'Rachel', 'good', 'to', 'meet', 'you', 'give', 'me', 'welcome', 'so', 'tell', 'us', 'what', 'you', 'do', 'hi', I'm, we're, 'working', 'on', 'admission', 'is'] Output: Everyone, for today's live office hours, we're joined by Adora and Vito, and I'll leave it to them to introduce themselves. I am a partner at Y Combinator; previously, I was a founder and CEO of a startup called Homejoy. Say, a virtual guard? I'm going to call, like, three experts. I was most definitely the director of product at Facebook, done a couple of startups, sold a couple in less than a bunch-load already. Nice to meet you, Rachel. Good to meet you. Give me a welcome, so tell us what you do. Hi, I'm - we're working on admissions. In the answer, I have made corrections related to capitalization, punctuation, and some minor rephrasing to make the sentence grammatically correct, as per the guidelines provided in the task.
