Answer:
x + (x + 12) = 40
Step-by-step explanation:
Given the total amount of special blend, coffee is forty pounds using Vanilla Dream beans and Strawberry Heaven beans.
Now, it is also given that the Vanilla Dream beans in the mixture are 12 more pounds than Strawberry Heaven beans.
In the mixture, if there are x pounds of Strawberry Heaven coffee beans, then the Vanilla Dream beans will be of (x + 12) pounds.
So, we can write the equation as, x + (x + 12) = 40. (Answer)

Answer:

Step-by-step explanation:
dP/dh = kP
dP/P = k dh
ln P = kh + C
Now, using the points given,
ln 101.5 = C, so C = 4.62
ln 87.3 = k*1000 + 4.62
k = -0.00015
So, we have
ln P = -0.00015 h + ln 101.5
P = 101.5 e^(-0.00015h)
