Studdy Solution

STEP 1

1. Sabah has a total of \$450 to spend on textbooks.
2. Each textbook costs \$75.
3. 4 textbooks can be checked out for free from the library.
4. We need to find the total number of books, represented by \( b \).

STEP 2

1. Determine the number of books Sabah can purchase.
2. Account for the free books from the library.
3. Write and complete the equation using the given information.

STEP 3

Determine the number of books Sabah can purchase with her budget.
Calculate the number of books she can buy by dividing her budget by the price per book:
$\text{Number of books she can buy} = \frac{450}{75}$

STEP 4

Account for the free books from the library.
Sabah can check out 4 books for free, so add these to the number of books she can purchase:
$b = \text{Number of books she can buy} + 4$

STEP 5

Write and complete the equation using the given information.
The equation to find the total number of books $b$ is:
$b = \left( \frac{450}{75} \right) + 4$
Calculate the number of books she can buy:
$\frac{450}{75} = 6$
So, the equation becomes:
$b = 6 + 4$
$b = 10$
The total number of books that Sabah can get for her classes is:
$\boxed{10}$
