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

Answer 1

1. 9 2/3 - 1/6=29/3-1/6=58/6 - 1/6=57/6

(57/6)/1/6 = 57/6 * 6/1 = 57

1.10 + 57*0.20 = $12.50

2. 9 - 1/6 = 54/6 = 1/6 = 53/6

1.10 + 53*0.20 = $11.70
