Final answer:
The relationship between the number of students and the total number of painted bricks can be represented by the equation b = 10 + 8s.
Step-by-step explanation:
The relationship between the number of students (s) and the total number of painted bricks (b) can be represented by the equation b = 10 + 8s. This equation shows that 10 bricks were already painted, and each student paints 8 more bricks. To find the total number of painted bricks, we add the initial 10 bricks to the 8 bricks painted by each student, multiplied by the number of students.
