My question is: As a freelancer, Katherine takes 20 hours to develop a website for her clients. Her junior, Naomi, takes 1/4 times more time to complete creating a similar website. If many clients required her to build their websites in a particular year, and she gave her junior 30 websites to develop, calculate the total number of hours Katherine's junior took to create the 30 websites. Your thoughts:
Katherine's junior takes 1 / 4 * 20 = 5 more hours to build a similar website as Katherine. The total number of hours Katherine's junior takes to build a website is 20 + 5 = 25 hours. If Katherine gave her junior 30 websites to build, her junior spent 30 * 25 = 750 hours on building the 30 websites. The final answer: 750.
