Question

Charlotte reads 4 books each week. Let b be the number of books she reads each week, and let ww be the number of weeks that she reads. Determine which variable is dependent and which is independent. Then, write an equation to model the situation, and make a table that shows the number of books read in under 6 weeks.

Answer 1

Answer and Step-by-step explanation:

Charlotte reads 4 books each week

b = number of books she reads each week

w = number of weeks that she reads

The number of books depends on the number of weeks, so

independent variable: w

dependent variable: b

b = 4w
