12. Erik is in the business of advertising. He charges a base fee of $30 for each visit and $50 per hour

for his labor. The total cost c(x) for a visit and x hours of labor is modeled by the function rule 

c(x) = 30 + 50x. Use the function rule to make a table of values and a graph.

x c(x)

Haley, we're just putting each of these values for x into the function and getting c(x)

 

I' ll do the first two and you can do the last two

 

c(0) =  30 + 50(0)  =   30 + 0  = 30

c(1)  = 30 + 50(1)  = 30 + 50   = 80

 

Got it ???

 

 

cool cool cool
