Muskaan had 157 dollars to spend on 6 books. After buying the she had 13 dollars. How much did each book cost?

nirvana33 [79]

Answer:

the cost of each book = $24

Step-by-step explanation:

(if all the books have the same price)

Let x be the price of one book

“She had $157 and After buying 6 books ,she was left with 13$“ means

“157 = 6x + 13”

now we have an equation to solve :

157 = 6x + 13

⇔ 157 - 13 = 6x

⇔ 144 = 6x

⇔ 24 = x

Using the data: 2, 2, 3, 3, 3, 4, 5, 6, 6, 10

sertanlavr [38]

$\huge{\boxed{4.5}}$

First, add all the numbers together. $2+2+3+3+3+4+5+6+6+10=\bf{44}$

Divide by the amount of numbers. $\frac{44}{10}=\boxed{4.4}$

$4.5$ is the closest, so that is the answer.
