Answer:
$3.26
Step-by-step explanation:
If 4.5 pounds cost $14.67
You divide 14.67 by 4.5 which gives you 3.26
They could look at the weight(take into consideration if the book is paperback or hardcover), the length, and the size of the font to estimate the size of the book.
Note that
10² = 100
0.08² = 0.0064
and
101.6064 = 100 + 1.6 + 0.0064
It also happens that
1.6 = 2 • 10 • 0.08
which means
101.6064 = 100 + 1.6 + 0.0064
101.6064 = 10² + 2 • 10 • 0.08 + 0.08²
101.6064 = (10 + 0.08)²
101.6064 = 10.08²
which means
√101.6064 = 10.08
which, to one decimal place, is approximately 10.1.
