In order for every book to be the same price they would have to be $9. But his cost 13. So I would subtract. 27-13=14. So he has $14 left. He still has to buy 2 more books so each of his sisters have a book. So he would have $7 to spend on each of them. Your answer would be yes he can spend $5 on each additional book.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Algebra II

Imaginary Roots: √-1 = i

Step-by-step explanation:

Step 1: Define

x² - 2x + 10 = 0

Step 2: Identify Variables

a = 1

b = -2

c = 10

Step 3: Find roots

Substitute [Quad Formula]: $x=\frac{2\pm\sqrt{(-2)^2-4(1)(10)} }{2(1)}$
Exponents: $x=\frac{2\pm\sqrt{4-4(1)(10)} }{2(1)}$
Multiply: $x=\frac{2\pm\sqrt{4-40} }{2}$
Subtract: $x=\frac{2\pm\sqrt{-36} }{2}$
Factor: $x=\frac{2\pm\sqrt{-1} \sqrt{36} }{2}$
Simplify: $x=\frac{2\pm6i }{2}$
Factor: $x=\frac{2(1\pm3i) }{2}$
Divide: $x=1\pm3i$
