Answer:
$106,714.29
$71,142.86
$71,142.86
Step-by-step explanation:
There's a total of 7 pieces that they invested (3 + 2 + 2 = 7) so you can do 249,000 / 7 to find what each piece was worth.
249000/7 = about 35571.43
(you always have to round money to 2 decimal places)
Then the amount each brother spent would be:
3 * 35571.43 = 106714.29
2 * 35571.43 = 71142.86
2 * 35571.43 = 71142.86
In 1 minute, 4 litre water leaves = 4*1000 cubic cm = 4000
so, the height decrease = Volume/area =
hence water level in cm falling per min = 0.318
hence water level in cm falling per hr= 0.318 * 60 = 19.09
