Alex has a part-time job where he works on different projects each day. On Monday, he worked on Project A for 1 hour and Project B for 2 hours. On Tuesday, he worked on Project A for 2 hours and Project B for 3 hours. On Wednesday, he worked on Project A for 3 hours and Project B for 4 hours. If Alex continues this pattern for the rest of the week, how many total hours will he have worked by the end of Sunday? Let's think step by step and output the final answer within \boxed{}.
