HELP MEEEEEEEEEEEE!!!!!!! Select the correct expression.
Steve reads 20 pages of his graphic novel per hour. If the book has 200 pages and he reads for d hours, which expression shows the number of pages he has left to read after reading for d hours?
If he reads 20 pages per hour, you would multiply it with d, as d is equal to an unknown number of hours, and to show the number of pages left after reading for d hours, you would subtract it
