We are tasked to solve for the total liters of water does Sameer was able to drink. To solve this we need to remember that 1 cup is equivalent to 0.236588 liters and then we need to perform the unit conversion. The solution is shown below:
total number of liters = 3 cups * (0.236588 liter / 1 cup)
total number of liters = 0.709764
The answer is 0.7 rounded to the nearest tenth.

Answer: 0.030921
In order to construct this equation, we will use the variables:
V to represent mixture volume (40 ml)
C to represent mixture concentration (0.32)
v₁ to represent volume of first solution (40 / 4 = 10 ml)
c₁ to represent concentration of first solution (0.2)
v₂ to represent the volume of the second solution (40 * 3/4 = 30 ml)
c₂ to represent the concentration of the second solution
We know that the total amount of substance, product of the volume and concentration, in the final solution is equal to the individual amounts in the two given solutions. Thus:
VC = v₁c₁ + v₂c₂
40(0.32) = 10(0.2) + 30c
f(x) = 
note the range is {1, 5, 25, 125 } which can be expressed as

}
the exponents being the domain { 0, 1, 2, 3 }
thus f(x) =
an exponential function
