Calculating Projected using max week number and Projected Annual against goal

I have one table that shows a date, that date's week number, category, and number of conversions for that entry

I am looking to sum up the conversions by Category, but with taking the Max week number, taking the sum of each category and dividing it by the max week number. Then using that number and multiplying it by 52 to get my projected annual number. **Note, my data has 2020 data, so I need the Max week number of 2021 or current year***

I also have another table-circled in red below-where the annual goal is listed for each category. I then want to take my Projected Number and show it against the projected annual number to show % attained against goal.
