Answer:
Shania has read the most pages.
Step-by-step 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.
