i am working on it

OpenStudy (michellemn):

Yea sorry I didn't realize you were already here.

oregonduck (oregonduck):

Part A: Well, each day it costs $93 to rent. So, y= x*93.

OpenStudy (michellemn):

ok...

oregonduck (oregonduck):

part a: y=(0<x<7)*$93+(7<x) * 89.30 -

OpenStudy (michellemn):

part b & c?

oregonduck (oregonduck):

i am working on it

OpenStudy (michellemn):

ok thank you

oregonduck (oregonduck):

Part A: 625-465=$160 he has to pay for 2 days=$160 rent paid for 1 day=260/2=$80 amount paid for 5days=8*5=$400 But he paid $465 Difference 465-400=$65 so every one has to pay $65+rent for the no. of days total rent for x days y=65+80 x (dollars) Part B: f(x)=65+80 x

OpenStudy (michellemn):

ok

oregonduck (oregonduck):
