To solve these parts, we first need to determine the price per book at both Book Store A and Book Store B.

Part A: Price per book at Book Store A

At Book Store A, the total cost for 25 books is $393.75. To find the price per book, we divide the total cost by the number of books:

\[ \text{Price per book at A} = \frac{393.75}{25} = 15.75 \]

So, the price per book at Book Store A is $15.75.

Part B: Price per book at Book Store B

The equation provided for Book Store B is \( y = 5.25x \). To find the price per book:

When \( x = 1 \),

\[ y = 5.25 \cdot 1 = 5.25 \]

So, the price per book at Book Store B is $5.25.

Comparing the prices:

  • Price per book at Store A: $15.75
  • Price per book at Store B: $5.25

Now let's answer the parts.

Part A: The price per book at Book Store A is higher.

Part B: The price per book at Book Store B is lower than the price per book at Book Store A.
