Answer:
<h2>The bathroom have enough water and shampoo.</h2>Step-by-step explanation:
This problem can solved just by replacing the given values into the give inequalities. The first inequality:
Refers to the maximum amount of water.
The second inequality:
Refers to the maximum amount of shampoo.
Then, the problem as is there's enough water en shampoo for 8 long-haired and 7 short-haired members, where <em>L </em>is long-haired and <em>S </em>is short-haired. Now, replacing this values in each inequality, we have:
Definitely, there's way enough water to 8 long-haired and 7 short-haired, because the maximum is 5600, and they only spend 980.
We see that there's enough shampoo too, because the maximum is 2.5, and these people only use 0.23.

<em>Therefore, the bathroom have enough water and shampoo for 8 long-haired members and 7 short-haired members.</em>

Check the picture below.
let's recall that in a Kite, the diagonals meet at 90° angles, therefore, we know the height of each of those 4 triangles, is 2.5 and 6, now, since the pair of triangles above are 45-45-90 triangles, we can use the 45-45-90 rule, as you see there, so, if the height is 2.5, then the base is also 2.5.
so, we really have 2 pair of triangles whose base is 2.5 and height of 2.5, and another pair of triangles whose base is 2.5 and height is 6, let's add their areas.
