Steven bought 6 books for $20.46. What is the constant of proportionality that relates the cost, y, to the number of books purchased, x?
To find the constant of proportionality, we need to divide the total cost by the number of books purchased.
Constant of proportionality, k = Total cost / Number of books purchased
Total cost = $20.46
Number of books purchased = 6
k = $20.46 / 6
k ≈ $3.41
So, the constant of proportionality that relates the cost to the number of books purchased is approximately $3.41.
