y = 3x + 5
? pages

Explanation:

Step1: Identify the value of x

Here, x represents the number of days, which is 7.

Step2: Substitute x into the equation

We have the equation \( y = 3x + 5 \). Substitute \( x = 7 \) into the equation:
\( y = 3\times7 + 5 \)

Step3: Calculate the result

First, calculate \( 3\times7 = 21 \), then add 5: \( 21 + 5 = 26 \).

Answer:

26
