$8.90
Step-by-step explanation:
$2 for the 1/4 mile. That leaves 5 3/4 more miles until 6 miles. He charges 30 cents for each additional 1/4 miles, and there are twenty-three 1/4ths in 5 3/4. So, 23*30=690, which is basically $6.90 because it's 690 cents.

a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
