which of following best define the two quantities that are measure to find the call rate phone company?
A.the quantity of price measured in dollars depends on the quantity of time measured in minutes
B. the quantity measured in minutes depends on the quantity of price measured in dollars
C. the quantity of time measured in minutes depends on the quantity of speed measured in calls per minute
D. the quantity of speed measured in calls per minute depends on the quantity of time measure in minutes
I think it's c.
the answers A.
Your Welcome :)
To determine the call rate of a phone company, we need to understand the two quantities being measured. Let's analyze each option to find the correct definition:
A. The quantity of price measured in dollars depends on the quantity of time measured in minutes.
This option suggests that the cost in dollars is determined by the duration of the call in minutes. However, we usually determine the call rate based on the price per minute, not the other way around. So, this option is not the correct definition.
B. The quantity measured in minutes depends on the quantity of price measured in dollars.
This option suggests that the duration of the call in minutes depends on the price in dollars. While the price may have some influence, it is primarily the customer's decision on how long they want to talk, not the other way around. Thus, this option is also not the correct definition.
C. The quantity of time measured in minutes depends on the quantity of speed measured in calls per minute.
This option does not align with the typical understanding of call rate calculation. The call rate usually represents the number of calls made per unit of time, so the speed of calls per minute would not directly determine the duration of a call in minutes. Therefore, this option is not the correct definition.
D. The quantity of speed measured in calls per minute depends on the quantity of time measured in minutes.
This option suggests that the number of calls made per minute (speed) is dependent on the duration of time in minutes. In this context, speed refers to the rate at which calls are being made, rather than the quantity of time spent on each call. This option does not represent the correct definition.
Based on the analysis above, none of the provided options accurately define the two quantities that are measured to find the call rate of a phone company.
