Answer:
The population of this country in 11 years will be 76972702.82
Step-by-step explanation:
The population of this country in 11 years can be calculated using the formula
Population in 11 years = Starting population x
Thus
Population in 11 years =50000000× =76972702.82
Using linear functions, it is found that the two plans cost the same for 5000 minutes of calling.
<h3>What is a linear function?</h3>A linear function is modeled by:
In which:
For Plan A, the cost is of $25 plus an additional $0.09 for each minute of calls, hence the y-intercept is , the slope is of
, and the function is:
For Plan B, the cost is of $0.14 for each minute of calls, hence the y-intercept is , the slope is of
, and the function is:
The plans cost the same for x minutes of calling, considering that:
The two plans cost the same for 5000 minutes of calling.
