The cost of a taxi is $1.80 plus $10 per eight of a mile .write an expression for the nth mile of a taxi ride.evaluate the expression for the cost of 4.5 miles.

Answer 1

I suspect you men .10 or 1.0 times 8 per mile not $10 per (1/8) mile but since you used 10 I will go along with $80 per mile

c = 1.8 + 80 m

c(4.5) = 1.8 + 80 (4.5)
