Hi swerve,

We're told that Jim's Taxi Service charges an initial fee of $2.25 at the beginning of a trip and an additional charge of $0.35 for each 2/5 of a mile traveled. We're asked for the total charge for a trip of 3.6 miles.

3.6 miles = 18/5, so we know that after the initial $2.25, there will be an additional (9)($0.35) = $3.15 charged.
$2.25 + $3.15 = $5.40

Final Answer: E

A. $3.15
B. $4.45
C. $4.80
D. $5.05
E. $5.40

Let's find how many "2/5 miles" are in 3.6 miles. Since 3.6 = 36/10 = 18/5, has (18/5)/(2/5) = 90/10 = 9 "2/5" miles; thus, the total charge for 3.6 miles would be 2.25 + 9 x 0.35 = $5.40.

Answer: E
