Kevin has already read 45 pages in his novel for English. He can read roughly 20 pages each hour. Shania has only read 5 pages so far, but she reads faster and can read roughly 25 pages each hour. Write an equation for the Kevin's reading pace and then write an equation for Shania's reading pace. After 20 hours, who has read more pages?

Answer:

Shania has read the most pages.

Explanation:

Following the formula y = mx + b.

Kevin already read 45 pages.

y = mx + 45

He reads 20 pages per hour, since it has per hour, we put it has "m"

y = 20x + 45

Shania already read 5 pages

y = mx + 5

Shania reads 25 pages per hour

y = 25x + 5

We need to find out how many pages they read after 20 hours, plug 20 into x.

Kevin

20(20) + 45 =

400 + 45 =

445

Shania

25(20) + 5 =

500 + 5 =

505

Shania read 60 more pages than Kevin.
