Well let's make x=#of gallons pumped in the smaller tank, so g+x=25
so x=25-g.
The question is a little confusing with the given info tho, but I'm assuming you mean this.
Y = 25x - 5 is the equation.
#1 B
#2 D
#3 A
See attached photo for step by step solutions :)
The answer is D. he ate 1/4, so there is 3/4 left. and there r 3 friends, so the answer is 3/4 divided by 3
