Answer:
36¢ per pound
Step-by-step explanation:
In 1995, the price per pound was ...
($24.7 million)/(15 million lb) = $1.6467/lb
In 2000, the price per pound was ...
($31,297,583)/(15,616,728 lb) = $2.0041/lb
The difference was ...
$2.0041 -1.6467 = $0.3574 ≈ 36¢ . . . per pound

In a calculation such as this, you want to keep enough significant digits so that you can appropriately round the final answer. Here, the result would be different if intermediate values were rounded to whole cents.

Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30
x = 15
Your age is 15 and your sisters is 17

Hi!
Let's make a small chart
18:15 left town B
19:15 1 hour
20:15 2 hours
21:15 3 hours
Since they actually arrived at 21:05, and not 21:15, we know it took more than 2 hours, but less than 3 hours.
Subtract the extra time
21:15-21:05 = 00:10
Since there are 60 minutes in an hour, (60-10=50) we know it took 2 hours and 50 minutes.
Another way to solve this would be to convert the times to decimals, and subtract,
21.05-18.15 = 2.9
Then convert the decimal to the time.
9/10 of an hour = 50 minutes
It took 2 hours and 50 minutes
Hope this helps! :)
