In a bookstore sidewalk sale, Georgia spent $62.82 on 9 books. The relationship between total cost (C) and the number of books (n) is expressed as C = (62.82 / 9) * n.
In a sidewalk sale at a bookstore, where rates vary directly with the number of books bought, the relationship between the total cost and the number of books purchased can be expressed as a linear equation. Let's denote the total cost as C and the number of books as n. The equation can be written as C = kn, where k is the constant of proportionality.
In this scenario, Georgia spent $62.82 when she bought 9 books. Substituting these values into the equation, we get 62.82 = k * 9. To find the value of k, we can solve for k by dividing both sides of the equation by 9: k = 62.82 / 9.
Now, with the value of k, we can express the relationship between the total cost and the number of books as C = (62.82 / 9) * n.
To find the cost when a different number of books are bought, simply substitute the desired value of n into the equation. This linear equation provides a straightforward way to calculate the total cost based on the number of books purchased during the sidewalk sale.
In conclusion, the relationship between the total cost and the number of books purchased during the sidewalk sale at the bookstore is given by the equation C = (62.82 / 9) * n, where C is the total cost and n is the number of books bought.
