Answer 1

The correct question will be - 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.

Given:

Rate of pages = 555

Hours = 4

Pages left to read = 350

To Find: Equation for relationship between the number of pages left and the number of hours.

Solution:

Let the time be = x hours

Let the number of pages left to read = y

Linear equation = y-y1 = m(x-x1)

According to question

y-350 = -55(x-4)

y-350 = -55x + 220

y = -55x + 220 + 350

y = - 55x + 570

Answer: The equation representing the relationship is y = - 55x + 570
