The correct answer is:  [C]:  " $4290.00 " .
_______________________________________
Explanation:
_________________________________________
Given:  principal, "P":  equals:  $14,300  ;
                 rate, "r" : equals:  7.5 %  = 7.5 / 100 = 0.075 ; 
                time, "t" (in years): equals:  4  ;
_________________________________________
What is the interest, "i" ? 
_________________________________________
  Note:  The formula:  i = P * r * t   .
_________________________________________
So, we plug in our given values for "P", "r", and "t", and solve for "i" (interest).
__________________________
i = ($14,300) *(0.075) * (4)  ;

i = $1,490 ;  which is answer choice:  [C]:  " $4290.00 " .

Find the rate of change of total​ revenue, cost, and profit with respect to time. Assume that​ R(x) and​ C(x) are in dollars. ​R
tresset_1 [31]

Answer:

Step-by-step explanation:

Given the Total revenue R(x) = 2x

Cost C(x) = 0.01x²+0.3x+30 where;

x = 30 and dx/dt = 9units per day.

Rate of change of revenue dR/dt = dR/dx • dx/dt

dR/dt = 2dx/dt

dR/dt = 2(9) = $18

Rate of change of revenue with respect to time is 18dollars/day.

Rate of change of cost dC/dt = dC/dx • dx/dt

dC/dt = (0.02x+0.3)dx/dt

dC/dt at x = 30 and dx/dt = 9 will give;

dC/dt = {0.02(30)+0.3}×9

dC/dt = (0.6+0.3) × 9

dC/dt = 0.9×9

dC/dt = $8.1

Rate of change of cost with respect to time is 8.1dollars/day

Profit = Revenue - Cost

Profit = 18-8.1

Daily Profit = $9.9
