Answer 1

Following is the information from the Closing Questions on the Assignment tab in Lesson 02.02. You will use this information and your answers to the Closing Questions to answer questions 1 through 5 and the matching exercise.

Your monthly cell phone bill is determined by a fixed monthly fee of $35 for 300 anytime minutes and $.40 for each additional minute used.

Dependent variables can be the result of more than one independent variable. Consider your phone bill as presented above. Aside from being charged for minutes over 300, you are charged $1.25 for each directory assistance call and $.75 per minute for long distance roaming calls. You also have to contribute at least $1.50 to the federally required Universal Service Fund per month and this value may vary on your phone bill but is not an independent variable.

Answer 15

but i have another uestion can u HELP?

Answer 16

we can list all the costs
fixed monthly fee of $35 <-- not a variable. i.e. it is a fixed number
$.40 for each additional minute used.<--- definitely will change from month to month
if you call x = minutes used, (x-300) is the additional minutes (if >0)

$1.25 for each directory assistance call. <--- variable. changes month to month

$.75 per minute for long distance roaming calls<--- variable.

$1.50 Universal Service Fund per month ... but is not an independent variable.
they say it's not variable, so we assume it's not variable.

How many variables?
1) add'l minutes
2) directory assistance
3) minutes of roaming calls

I would say 3 independent (i.e. input) variables.
