Answer:
462.5 pages
Step-by-step explanation:
You find out how many books she reads in 1 day then you can multiply it by 5 to get 5 days.
If she reads 185 in 2 days. Divide 185 by 2 to get 1 day.
185/2 = 92.5 pages
Now multiply 92.5 by 5 to get how many pages she read after 5 days.
92.5 x 5 = 462.5 pages
