Answer:
297 miles
Step-by-step explanation:
cost = 0.78 cents per mile + base fee
y = 0.78x + 15.88
247.65 = 0.78x + 15.88
subtract 15.88 from both sides
231.77 = 0.78x
divide by 0.78 on both sides
x = 297.14120256
297 miles

1800000-40000/40000 = x/100
1760000/40000 = x/100
176*25/4*25 = x/100
X= 4400% increase
