To find out how much each book cost first we will subract to find out how many 2 books cost. Then we will divide. last but not least we will check our wok. Lets do it:-

30 - 8.95 = 21.05
21.05 - 7.25 = 13.80

CHECK OUR WORK:-

13.80 + 7.25 = 21.05
21.05 + 8.95 = 30
We were RIGHT!!!

Now lets divide:-

13.80 ÷ 2 = 6.90
1 book costs $6.90.

CHECK OUR WORK:-

6.90 × 2 = 13.80
We were RIGHT!!!!

So, 1 book costs $6.90.

Hope i helped ya!!
