Determine the cost of a taxi trip of 9 miles if the fare is $1.10 for
the first 1/6 mile and $.20 for each additional 1/6 mile (or fraction).
a. $1.80
b. $10.50
c. $9.30
d. $11.70
First, we need to determine how many 1/6 miles are in 9 miles.
9 miles = 9 x 6 = 54 sixths
Then, we can subtract the initial 1/6 mile from the total distance:
54 sixths - 1 sixth = 53 sixths
Finally, we can multiply the remaining distance by the per-sixth fare:
53 x $.20 = $10.60
Adding the initial $1.10 fare, the total cost of the taxi trip is:
$1.10 + $10.60 = $11.70
Therefore, the correct answer is d) $11.70.
