Question

Tyler needs to buy a book for school that costs $13 he also wants to get a book for each of his two sisters and he wants to be sure he spends the same amount on each of their books. He only has $27 to spend. Let b represent the amount he can spend on each additional book

Answer 1

`b = \$7`

Explanation:

Given that:

Cost of book that Tyler wants to buy for his school = $13

He wants to buy books for his sisters as well.

Total amount of money present with Tyler = $27

Money to be spent on books for his sisters is same and is represented as
`b`.

To find:

The value of
`b`.

Solution:

As per question statement, the sum of all the books bought must be equal to $27.

The sum of money spent on all the books = Cost of Tyler's book + Cost of books for his sisters

`\Rightarrow \$13 + b + b = \$27\\\Rightarrow \$13 + 2b = \$27\\\Rightarrow 2b =\$14\\\Rightarrow b =\$7`

Therefore, Tyler must spend $7 on each of her sister's books.
