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

D (.9, 2.4)

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
