Joseph pays $20 for his base phone plan in addition to the $0.23 per text. micki pays $10 for her phne plan plus $0.15 per text. what is the function for joesphs phone plan and for mikis phoen plan?

Not really Specific in asking in what way you want it answered... So here is what Im able to understand.

Function

Joseph : 20 + .23x = y

Micki : 10 + .15x =y

Hope this is what your asking...

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
