A company makes women's shoes. The price of the duty-free sale of a pair of shoes
is set at 180 €. The total production cost C (x), in euros, is expressed as a function of the number x of
pairs of shoes sold by:
C x () = + 1.5 1 x x5 +1350 2 with x ∈ [] 10; 80

c. In an orthogonal coordinate system having a unit of 1 cm for 10 pairs of shoes on the abscissa and 500 €
for 2 cm on the y-axis, represent function B set to [] 10; 80.
d. Graphically determine the solutions of equation B (x) = 3000.
