We can find this out by taking the total (23.70) and dividing it by the 5 band members, getting the number 4.74. Now we do this again, but with the extra band member we get 3.95. Now the last step it 4.74 - 3.95, which is 0.79. So each band member payed 0.79 less than normal.
The converse is: If x2=100, then x=-10
The answer would be option D.
You can use desmos.com/calculator for graphing these equations.
Easy,
100 gallons=800 pints
There are 8 pints to a gallon. Since 100 gallons is the same as 800 pints, that is larger than 400 pints, Witch is also 50 gallons.
So ill say 100 gallons are bigger. :)
