Answer:
The % growth rate is 15.8%.
Step-by-step explanation:
Let the function is given by , where f(w) is the number of a specific product produced after w weeks.
Now, given for w = 0, f(0) = 190 = a
So, the function becomes ............. (1)
Now, it is also give that at w = 1, f(1) = 220.
So, from equation (1) we get,
⇒ b = 1.15789.
Now, b = 1 + r
⇒ 1.15789 = 1 + r
⇒ r = 0.15789
Therefore, the % growth rate is 0.15789 × 100% = 15.8% (Approx.)
Given:
Investment on equipment = $98,000
Cost of each unit = $12.20
Selling price of each unit = $16.98.
To find:
(a) The total cost C as a function of x.
(b) The revenue R as a function of x.
(c) The profit P as a function of x.
Solution:
Let x be the number of units produced and sold.
We have,
Fixed cost = $98,000
Variable cost = $12.20x
Total cost = Fixed cost + Variable cost
Therefore, the cost function is .
Selling price of each unit = Revenue from each unit = $16.98.
Total revenue = Revenue from x units
Therefore, the revenue function is .
Profit = Revenue - Cost
Therefore, the profit function is .
