D. You have to since the sign is opened to the left, go right. So, Y>-1.5
It’s to the opposite
Y = 25x + 35
y = 5x + 45
Thus,
25x + 35 = 5x + 45
25x - 5x = 45 - 35
20x = 10
x = 10/20 = 1/2
y = 5x + 45
y = 2.5 + 45
y = 47.5
Thus, x = 1/2, y = 47.5
(a) $0.06 per kilogram

I'm a little confused by this. 1/2 is too big, but 1 1/2 is too small?
