Answer:
A. 1200
Step-by-step explanation:
Since 10 times 3 is 30, then 400 times 3 is 1200. Hope I helped!
Answer:

Step-by-step explanation:
The marginal cost function, C'(x), is the derivate of the cost function, C(x).
Therefore, we can obtain the cost function by finding the integral of the marginal cost function:

Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:

The formula is
A=p e^rt
A future value 900
P present value 800
E constant
R interest rate 0.11
T time?
We need to solve for t
T=[log (A/p)÷log (e)]÷r
T=(log(900÷800)÷log(e))÷0.11
T=1.07 years round your answer to get 1 year
