To find the number of books Sarah has when \( t = 5 \), we can substitute \( t \) with 5 in the expression \( 4t + 7 \):
\[
4(5) + 7
\]
Calculating this step-by-step:
1. Multiply \( 4 \) by \( 5 \):
\[
4 \times 5 = 20
\]
2. Add \( 7 \) to \( 20 \):
\[
20 + 7 = 27
\]
Thus, when \( t = 5 \), Sarah has \( 27 \) books.
The answer is **A. 27**.
