Revenue from selling the posters:
y = 4x

Cost of producing the posters:
y = 1/2x + 280

Equate and solve for x
$4x = \dfrac{1}{2}x + 280$

$4x- \dfrac{1}{2}x = 280$

$3\dfrac{1}{2}x = 280$

$\dfrac{7x}{2} = 280$

$7x =560$

$x = 560 \div 7$

$x = 80$


Answer: Jason must sell 80 of the posters so that the cost and revenue are equal.
