The correct answers are, <u><em>A, D, and E.</em></u>
He would pay more in this point because 20% is more than 10 US dollars
J =Jorge
if the sum is no less than 25 then the best result to the question is Jorge is 8, while his brother is 9, but to put that in an inequality it'll be 2x+2j - 2 is greater than or equal to (couldnt use intended symbol)...25
Volume of an iceberg = 7685 cubic feet
Since, density of ice = 0.917 
We have to determine the mass of the ice.
Since density = 
Since the unit of density is in
, first we will convert the density unit in kilogram.
Since, 1 kilogram = 1000 gram
Therefore, density = 
= 0.000917 
Since, the density unit is in cubic centimeter. We will convert it into cubic feet.
1 cubic centimeter = 0.00003531466 cubic feet
Therefore, 0.000917
= 0.000917 x 0.00003531466
= 0.0000000323
.
Now, mass = 
= 0.0000000323
7685
= 0.000248
=0.00025
.
Therefore, the mass of ice is 0.00025
.
