Volume- LxWxH
30x10x50= 15000
x/10 + x/4 = 21 /*40
4x + 10x = 840
14x = 840
x = 60 = total number of points the team scored
268 gallons are remaining. The equation would be y=324-7x, with x being 8. 7(8) is 56, and then you take away 56 from 324, which then gives you 268 gallons remaining
It would be: 178.90 * 3.75%
= 178.90 * 0.0375
= 6.71
In short, Sales tax would be $6.71
Hope this helps!

If you need an explanation as to how I did, you just add 4 to the x coordinate and subtract 5 from the y coordinate since going down is negative.
