Answer: The correct answer is A
Step-by-step explanation: The correct equation is Choice A.
You are solving for b, which is the number of books read in a week.
We are given that 3 books are read each week, so that is 3w.
Putting it together, b = 3w
Next, we substitute 18 weeks into the equation to solve for how many books will be read in 18 weeks: b = 3 x 18, b = 54
