B can finish the job alone in 24 days.
In work-rate problems, a certain person can complete a fraction of the job for a specific timeframe. As stated in the problem, A and B can finish the job by working together for 8 days. It must be noted that the fraction of the job they can finish individually per day is additive.
A can complete the work in 12 days and finish 1/12 fraction of a job per day. This can be substituted directly to the equation to solve for the time B needed to finish the work.
This means that B can do 1/24 fraction of the job per day and can completely finish the job in 24 days.

Answer:
7,470
Step-by-step explanation:
<u>Step 1: Convert all into inches</u>
1 feet = 12 inches
2 feet = x inches
<em>Cross multiply</em>
x = 24 inches
1 yard = 36 inches
13 yard = x inches
<em>Cross multiply</em>
x = 468 inches
<u>Step 2: Add all inches together</u>
24 + 468 + 6 = 498 inches
<u>Step 3: Multiply by 15</u>
498 x 15 = 7,470
Therefore, the answer is 7,470.
