Let's write f(x)=4x-1, g(x)=-3x+5

We see f(.8)=2.2, g(.8)=2.6 close, with g a bit bigger

then f(.9)=2.6, g(.9)=2.3 also close, with f a bit bigger

We see f and g crossed somewhere between .8 and .9 at a value beween 2.2 and 2.6, so I'd guess a meet near (0.85, 2.4). Closest answer is

Answer: D (.9, 2.4)

$P = 0.5*0.6 = 0.3$
