Answer: The answer is e. $215,000.
Explanation: Based on the information provided in the question, see the cash flows statement below:
XYZ Cash Flows Statement
Net income $180,000
Increase in account receivable (15,000)
Increase in accounts payable 50,000
Cash flows from operating activities $215,000
- Note that the purchase of equipment of $50,000 cash would not be considered under cash flows from operating activities but would rather be considered under cash flows from investing activities.

Answer:

Explanation:
Given:
Total population after time (P) = 100% + 50% = 1 + 0.5 = 1.5
Starting population (p) = 100% = 1
Number of year (t) = 4 year
rate of growth = r
Computation:
Exponential growth function for population :
P =
1.5 = 
1.5 = 
From taking log:
4r = ln(1.5)
