Answer:
You did not provide the tables to choose from, but the relationship between number of books and total price is that each book is 14.25. Hope that helps at least.
Equation = a² + b² = c²
a = 80
b = 39
c = Diagonal
a² + b² = c²
80² + 39² = c²
6400 + 1521 = c²
c² = 7921
c = √7921
c = 89
Answer = 89 units
6 is in the hundredths place (1/100) in 4.768... so 6 has the value of 0.06
