Answer: it’s C
Step-by-step explanation:
The correct equation is:

The volume of second cylinder is 256 centimeter cubed
<em><u>Solution:</u></em>
Given that,
One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder
The first cylinder’s volume is 216 centimeter cubed
From given,
Let "x" be the volume of second cylinder
Therefore,
Volume of first cylinder = 7/8 of the volume of a second cylinder - 8


Thus the volume of second cylinder is 256 centimeter cubed
The cost to equip all the stations in the chemistry lab is calculated as: $393.75.
<h3>How to Calculate Total Cost?</h3>
In this scenario, we are given the following:
Total number of stations = 21 stations
Length of rubber tubing each of the stations in the chemistry lab needs = 5 feet
Total length of rubber tubing needed for all stations in the chemistry lab = 21 × 5 = 105 feet
Cost of 1 rubber tubing = $6.25 per yard
Convert 5 feet to yard:
1 yard = 3 feet
x yard = 5 feet
x = (5 × 1)/3
x = 5/3 feet.
So, the cost of 1 rubber tubing = $6.25 per 5/3
Cost of total length of tubbing needed = (105 × 6.25)/5/3 = (105 × 6.25) × 3/5
Cost of total length of tubbing needed = $393.75
Therefore, the cost to equip all the stations in the chemistry lab is calculated as: $393.75.
