Answer:
50 kg water.
Step-by-step explanation:
We have been given that the number of kilograms of water in a human body varies directly as the mass of the body.
We know that two directly proportional quantities are in form
, where y varies directly with x and k is constant of variation.
We are told that an 87-kg person contains 58 kg of water. We can represent this information in an equation as:

Let us find the constant of variation as:



The equation
represents the relation between water (y) in a human body with respect to mass of the body (x).
To find the amount of water in a 75-kg person, we will substitute
in our given equation and solve for y.



Therefore, there are 50 kg of water in a 75-kg person.
I will assume it is 2.5% interest rate over 2 years and not per year. If this isn’t the case then let me know.

Well $1250 divided by 100 = $12.50
This is 1%-

-
To make 2.5% we do-> $12.50 x 2.5= $31.25
This makes our interest rate $31.25

To get our total amount.....
$1250 + $31.25 = $1281.25
