aaronq · Answer

you wanna subtract the expenses from the profit so, find f(x)-g(x) when x=105

anonymous · Answer

huh?

aaronq · Answer

f(x) = 33x + 16; (x) = 4x + 50

profit=f(x)-g(x)= 33x + 16 - (4x + 50)

=33x + 16 - 4x - 50

=29x-44?

aaronq · Answer

yeah, now find what it is when x=105

profit=29(105)-44

aaronq · Answer

it's 29x-34, not -44

anonymous · Answer

lol. okay. Then divide both sides by 29?

aaronq · Answer

you're not solving for x, just multiply and subtract

profit = 29(105)-34
