Question
thumb_up100%
A certain telephone company charges $0.10 for the first minute of a long-distance call and $0.07 for each additional minute or fraction thereof. If C is the cost of a call and x is the length of the call in minutes, find the cost as a function of x, and skethch a graph. Assume that x <= 3. Find any points of discontinuity. Would these points affect your behavior?
The function I came up with is f(x) = (x*60-60)/60(.07)+.10... Does that work? I'm confused on how to find points of discontinuity however.

- In order to write the total cost as a function of one variable, we must find a relationship between X and Y Since the company prints X books in each of the Y printing runs, the total number of books printed is XY, so we must have XY= ____. . We can use this to express Y as a function of X.arrow_forwardGetting going in the morning was probably hard for folks on the Overland Trail (just as it may be for you today), so coffee was a highly valued commodity. The Cazneau family starts their journey with a supply of 30 pounds of coffee. When they arrive at Sutter's Fort in California, 188 days later, they have only 3 pounds left. 1. Draw a graph showing the amount of coffee remaining as a function of the time elapsed since the start of the journey. For simplicity, assume the Cazneaus consume coffee at a constant rate. 2. Find the average amount of coffee consumed per day. 3. Develop an equation for the function represented by your graph. Find the slope of your graph. 4. 5. Suppose that at the beginning of their 188-day journey, the Cazneaus are 1600 miles from Sutter's Fort. a. How many miles per day do they travel? For simplicity, assume they travel the same distance each day. b. Of course, as the Cazneaus travel, their distance from Sutter's Fort decreases.
