Due tommrow❗❗❗ somaya is reading a book with 240 pages. she has plans read 90 pages each day until she finishes the book. a. sumaya writes the equation 330 =-20d to find the number of days she will need to finish the book. identify the errors that sumaya made

I believe that Sumaya should've done 240=90d because the book has a total of 240 pages and she plans to read 90 per day so if you plug in a number for d, it would show how far along in the book she would be in a certain amount of days. I can't guarantee its right but it seems right based off of problems I've done like this in the past.
