Step-by-step explanation:

Step one

225-175 to get 50 pages per every 2 night for Amelia

Step two

224- 160 to get 64 pages every 2 night for Carmen

Step 3

Add 225 and 50 to get 275

Step 4

Add 224 and 64 o get 288

Step 5

Subtract 275 from 288 to get 13

Carmen’s book has 13 more pages.

Step-by-step explanation:

After night 4, Amelia has 175 pages remaining.  After night 5, she has 150.  This means she reads 175-150 = 25 pages per night.

After night 4, Carmen has 160 pages remaining.  After night 5, she has 128.  This means she reads 160-128 = 32 pages per night.

Let x be the total number of pages in Amelia's book.  She reads 25 pages per night; after 4 nights, she has 175 pages remaining.  This gives us the equation

x - 25(4) = 175

x - 100 = 175

Add 100 to each side:

x - 100 + 100 = 175+100

x = 275

Amelia's book has 275 pages.

Let y be the total number of pages in Carmen's book.  She reads 32 pages per night; after 4 nights, she has 160 pages remaining.  This gives us the equation

x - 32(4) = 160

x - 128 = 160

Add 128 to each side:

x - 128 + 128 = 160 + 128

x = 288

Carmen's book has 288 pages.

This means Carmen's book has 288-275 = 13 more pages.
