39) Graph the following linear inequality.
40) Behemoth Backpacks, Inc. finds that the cost
x + 4y > 0
to make x backpacks is modeled by the
linear equation C = 80x - 4,108, while the
revenue produced from them is modeled by
the linear equation R = 162x (C and R are
measured in dollars). What is the smallest
whole number of backpacks, x, that must be
sold for the company to show a profit?
