Question 202980: An appliance repair service uses the formula c=50n+80 to determine the labor cost for a service call, where c= the cost in dollars and n= the number of hours
a find the cost for n=0,1, and 2 hours
b find the slope and c-intercept for the line c= 50n+80
c interpret tyhe slope and c-intercept

You can put this solution on YOUR website! An appliance repair service uses the formula c=50n+80 to determine the labor cost for a service call, where c= the cost in dollars and n= the number of hours
a find the cost for n=0,1, and 2 hours
n=1: c = 50*1+80 = 130
n=2: c = 50*2+80 = 180
n=3: c = 50*3+80 = 230
-------------------------------------------------
b find the slope and c-intercept for the line c= 50n+80
slope = 50; c-intercept = 80
-------------------------------------------------
c interpret the slope and c-intercept
As n increases "1", c increases 50
When n = 0 c = 80
=====================================================
