Maintaining flexibility will aid in muscle and joints health, which can keep older adults doing their favorite daily activities and remain independent.
Answer:

Explanation:
So, we are looking for a linear equation. As we know Equation of a line has different forms, let´s use slope-intercept form:

Where C is the total cost as a function of t, t is the amount of airtime in minutes, m is the slope and b is the y-intercept
Now, let´s use the data provide in order to find m and b:
(E1)
(E2)
We have a 2X2 system of equations, let´s solve it using elimination method:


Replacing b in (E1) or (E2):


Knowing the slope m and the y-intercept b the linear model that represents the total cost as a function of t is:

You can check the results evaluating t=150 and t=300, the results must be 40 and 55 respectively
Answer:
d) Trialibility.
Explanation:
Under trialibility a customer can take trial of the product and then, take a decision whether to adapt the product or not.
In this manner, company saves itself from launching the product at complete market level, and incurring cost at the same level.
In the given instance also, company, launches the product on a trial basis and the launch is limited to specific users, that is the product is on trial and then the launch will be made at full commitment only when the trial period will be successful.
Therefore, correct term is
Trialibility
