Answer:

297.1410256 = m

Explanation:

charge = 15.88 + .78m where m is the miles driven

247.65 = 15.88 + .78m

Subtract 15.88 from each side

247.65-15.88 = .78m

231.77 = .78m

Divide each side by .78

231.77/.78 = m

297.1410256 = m

Answer:

297 miles

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
