a.
To calculate: Write an equation that gives the average cost of a printed photo as a function of the number of photos printed.
The equation that gives the average cost of a printed photo as a function of the number of photos printed is
Given information:
The printer costs =
The ink and paper cost about
Concept used:
The concept of algebraic equation.
Calculation:
The printer costs =
Let,
To calculate the price per every other photo,
Since each photo cost
To find average price per photo, divide last step with number of photos
Conclusion:
The equation is
b.
To graph: Use the graph to estimate the number of photos have to print before the average cost drops to
Given information:
The printer costs =
The ink and paper cost about
Average price per photo:
Graph:
The amount of photos needs to print before the average cost drops to
be found by looking at the intersection of the two curves in the graph:
Interpretation:
Need to print about 22 pages.
c.
To calculate: What happens to the average cost as the number of photos printed increases?
It approaches
Given information:
The printer costs =
The ink and paper cost about
Average price per photo:
Explanation:
The average cost as the number of photos printed increases; the average cost approaches the asymptotic value:
