5 bars of soap for $4.00 because more money is save.
The easiest way to find answers for questions like these is to convert them to improper fractions, solve, and then convert them back to mixed numbers (if the question required it). When we convert these to improper fractions, we have 7/4 and 19/8. We can then find the least common denominator of the 2 so that we can solve. The least common denominator is 8, and since we are multiplying the 4 by 2 to get it there, we must also multiply the 7 by 2. Now we have 19/8-14/8. At this point, we can use simple subtraction to subtract the numerators and get 5/8.
To summarize, Cameron used 5/8 more acid in the second experiment.

Answer:
Step-by-step explanation:
The volume of a cylinder can be determined using the formula V = Bh where B is the area of the base of the cylinder and h is the height.
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
In the real world, calculating volume is probably not something that you will use as often as calculating area.
However it can still be important. Being able to calculate volume will enable you to, for example, work out how much packing space you have when moving house, how much office space you need, or how much jam you can fit into a jar.
It can also be useful for understanding what the media mean when they talk about the capacity of a dam or the flow of a river.
