Question

The cost of 7 books was $154.40. How much does each book cost?

Answer 1

Answer:

Each book costs about $22.06

Step-by-step explanation:

[] We can set up a proportion, and then use cross-multiplying to solve:

$\frac{7books}{154.40dollars} =\frac{1book}{x}$

7x = $154.4

x = 22.05714

x ≈ $22.06
