QUESTION: 263

A taxi company costs $2.75 for the first quarter-mile and 12.5 cents for each additional quarter mile. What is the maximum distance you can travel with $6.50?

4 miles
5 3/4 miles
6 1/2 miles
7 3/4 miles
8 1/4 miles

Answer(s): D

Explanation:

Since you spend $2.75 for the first quarter mile, you have $3.75 (6.5 – 2.75) left to spend on ¼ mile intervals.
$3.75 divided by $.125 equals 30 quarter miles. The 30 miles, plus the initial quarter mile, makes a total of 31quarter miles. 31 quarter-miles equal 7.75 miles.

A photo-mat shop charges $0.55 for the first photo inside a film, and 40% cents less for each additional photo. How many photos can we develop with $52.58 if each film contains 36 photos?

4 films and 12 photos
5 films and 6 photos
5 films and 14 photos
6 films and 4 photos
6 films and 28 photos

Answer(s): A

Explanation:

Each film costs: 0.55 + 35 x (60% of 0.55 $ is 0.33) = 0.55 + 11.55 = 12.1$ per film. 52.58$ = 4 x 12.1$ + 4.18$.
4.18$ - 0.55$ = 3.63$. 3.63$/0.33$ = 11 All together gives 4 films + 12 photos.
