Answer:
A. $7.17
Step-by-step explanation:
We have been given that a mechanic uses his credit card to pay for a compressor that costs $477.95 and does not pay on it until the second month.
We will use compound interest formula to solve our given problem.
where,
A = Final amount after T years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Periods of compounding,
T = Time in years.
Let us multiply our given rate by 12 to get APR and convert it in decimal form.
Since 1 year equals 12 months, so 1 month will be 1/12 year.
Upon substituting our given values in above formula we will get,
Now let us subtract principal amount from the final amount to get the monthly interest charge at the end of 1st month.
Therefore, the monthly interest charge be at the end of the first month will be $7.17 and option A is the correct choice.
Answer:
(3.8)
Step-by-step explanation:
Given
See attachment for grid
Required
Which point is on Veronica's path
On the attached grid, I plotted each of the coordinate pair (i.e the given options, A to D) on the grid.
By observation. we can see that:
A is on the vertical line (y intercept)
B is on the second quadrant
C is just few points to the left of the given path
D represents Verlonda's house
<em>Hence, the required coordinate pair is: (3.8)</em>
Answer:
Step-by-step explanation:
If the profit realized by the company is modelled by the equation
P (x) = −0.5x² + 120x + 2000, marginal profit occurs at dP/dx = 0
dP/dx = -x+120
P'(x) = -x+120
Company's marginal profit at the $100,000 advertising level will be expressed as;
P '(100) = -100+120
P'(100) = 20
Marginal profit at the $100,000 advertising level is $20,000
Company's marginal profit at the $140,000 advertising level will be expressed as;
P '(140) = -140+120
P'(140) = -20
Marginal profit at the $140,000 advertising level is $-20,000
<u>Based on the marginal profit at both advertising level, I will recommend the advertising expenditure when profit between $0 and $119 is made. At any marginal profit from $120 and above, it is not advisable for the company to advertise because they will fall into a negative marginal profit which is invariably a loss.</u>
