Answer:8 dollars per book

Step-by-step explanation:

Keith started with 81 dollars, and hadd seventeen dollars left over. Subtract 81 from 17 and you will get how much he spent. 64 dollars spent to buy books. Next you would divide 64 by 8, because 8 is the amount of books he bought. 64 divided by 8 is 8. So each book cost 8 dollars

Equation: (81-17) divided by 8

To find the percentage of change, find the difference between the two by subtracting 31 from 62, leaving you with 31. Divide 31 by 62, which should give you 0.5. Multiply this number by 100, leaving you with 50%. There is a 50% change from 62 trees to 31 trees.
