The cost is $0.063.
Explanation:
First, we need to express the volume of the hangar in liters. We know that 1 ft³ = 28.31 L, so using proportions:
The amount of vanillin required would be:
Finally, the price for such amount of vanillin is:
I made a cup of coffee on the stove and when I went to check on it four hours later, there was no more water in the kettle.
