To find the constant of proportionality, we need to calculate the cost per bottle for each scenario.
Cost per bottle = Cost / Bottles Manufactured
For the first scenario:
Cost per bottle = 0 / 0 = 0
For the second scenario:
Cost per bottle = 20 / 25 = 0.8
For the third scenario:
Cost per bottle = 40 / 50 = 0.8
For the fourth scenario:
Cost per bottle = 80 / 100 = 0.8
The cost per bottle is constant at $0.80. Therefore, the constant of proportionality is 0.80, which corresponds to option B.
