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:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
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.

The correct answer is option B which is the actual product is about StartFraction 1 over 18 EndFraction less than the estimate.
<h3>What are fractions?</h3>The fraction is defined as the division of the whole part into an equal number of parts. here we have the following information Vassil rounded to the nearest half to estimate the product of Five-eighths and StartFraction 8 over 9 EndFraction.
E = = 0.55
Thus the product of the fraction estimated in the nearest half is,
0.5×1= 0.50
Therefore the correct answer is option B which is the actual product is about StartFraction 1 over 18 EndFraction less than the estimate.
