Any even number raised to any power will remain even. (e.g. 2² = 4, 2³ = 8, etc)
Any odd number raised to any power will remain odd. (e.g. 1² = 1³ = ... = 1, 3⁴ = 81, etc)
So 
will always be even, since both
[even] - [odd] = [odd]
and
[odd] - [even] = [odd]
S1=$70/20gal=$3.50 per gallon
s2=$33.50/(50/4)gal=$2.68 per gallon
s3=$48.75/(15+8)gal=$2.12 per gallon
So supplier #3 has the best deal.
Y=-x+b
plug in x = 4 and y = 1 to find b
1 = -4 + b and we know that if you add 5 and -4 you get 1. So ...
5 = b so if we plug that in
y= -x + 5
which is the same as y + x = 5, So it would be A
