Answer:
Check the explanation
Explanation:
C(x) = 0.06x^2 - 6x + 218
Its a quadratic function , minima would occur at vertex.
x is no. of digital cameras
x = -b/2a = -(-6/2*0.06) = 50 cameras
Minimum marginal cost : C(50) = 0.06(50)^2 - 6*50 + 218 = $ 68
Answer:
The answer is 72.9 dollars.
Explanation:
The reserve ratio of 10% means that bank must keep 10% percent of amount deposited in bank to meet emergency payments and can lend the remaining 90% to other banks. So the second bank can lend 81 dollars that is 90% of 81 dollars. As per this rule second bank has 72.9 dollars (90% of 81) to lend.

Answer:
time required is 7.70 years
Explanation:
given data
interest rate = 9%
solution
we know with the compounded continuously rate r and time t amount is
A(t) = A(o)
.................1
and we have given amount is double so
A(t) = 2 A(o)
so from equation 1 put the value and we get here
2 A(o) = A(o) 
ln(2) = 0.09 t
solve it we get time
time t = 7.70 years
so time required is 7.70 years
