Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read. Let y represent the number of pages to read after x hours

We can write the expression as: y = 570 - 55x

At the time, there were 350 pages left so we can add to find the total amount of pages.

350 + 220 = 570 pages

Naoya can read 55 pages per hour. This can be represented by 55x, where "x" is the amount of hours he reads for.

Best of Luck!

y = 570 - 55x

Step-by-step explanation:

y = T - 55x

350 = T - 55 (4)

T = 350 + 220

T = 570

y = 570 - 55x
