Answer:
Volume of 3% alcohol = 80 ml
Volume of 8% alcohol = 120 ml
Step-by-step explanation:
Final volume of 6% alcohol solution = 200 ml
Let the volume of 3% alcohol volume = a ml
Therefore, volume of 8% alcohol = (200 - a) ml
Equation for the given situation will be,
3a + 8(200 - a) = 6×200
3a + 1600 - 8a = 1200
1600 - 5a = 1200
5a = 400
a = 80 ml
Therefore, volume of 3% alcohol to be used = 80 ml
And volume of 8% alcohol to be used = (200 - 80) = 120 ml

Answer:
A(t) = 300 -260e^(-t/50)
Step-by-step explanation:
The rate of change of A(t) is ...
A'(t) = 6 -6/300·A(t)
Rewriting, we have ...
A'(t) +(1/50)A(t) = 6
This has solution ...
A(t) = p + qe^-(t/50)
We need to find the values of p and q. Using the differential equation, we ahve ...
A'(t) = -q/50e^-(t/50) = 6 - (p +qe^-(t/50))/50
0 = 6 -p/50
p = 300
From the initial condition, ...
A(0) = 300 +q = 40
q = -260
So, the complete solution is ...
A(t) = 300 -260e^(-t/50)
