I would go with D, it looks like it is the most linear out of the rest, Hope it helps:)
There<u> four sixties </u> the remainder is 4
The line which rises to the left has slope of -1/3 and y intercept of 2 so we have
y = -1/3x + 2
3y = -x + 6
x + 3y = 6
Shading is below and the line is solid so the inequality is
x + 3y ≤ 6
The other line has equation
y = 3x - 1
and inequality is
y ≥ 3x - 1
The answer is B
60% is answer...20% is taken each year so After 2 yrs it's 40% less 100-40 is 60
