Answer :
Final answer:
The initial number of textbooks in the bookstore was 1,245 textbooks.
Explanation:
To find the initial number of textbooks in the bookstore, we can set up an equation. Let's assume that the initial number of textbooks is x.
After selling one-third of its textbooks, the bookstore has 830 textbooks left. This means that two-thirds of the textbooks were sold, which is equal to 830.
We can set up the equation: (2/3)x = 830
To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2.
x = 830 * (3/2) = 1245
Therefore, the initial number of textbooks in the bookstore was 1,245 textbooks.
