Question 315544
F(x) = 2.09x + 15.50 =214.05 
A. We sold 95 hats that year. How much was our total bill from Signature Shirts? (Yes, they do hats, too…)
F(95) = 2.09(95)+15.50 = 
--------------------------------------- 
B. How many hats would we have sold had we paid Signature Shirts $341.54?
341.54 = 2.09x + 15.50
solve for "x"
----------------------------------------- 
C. What is our slope of this function?
2.09
------------------------ 
D. What is our y-intercept?
15.50
------------------------ 
E. What does the y-intercept represent?
The cost of getting set up  before you sell any hats.
------------------------------- 
6. Our equation y = 2.09x + 15.50 represents our charge for hats. An estimate from a competing company, Lotsa Hats, was -1.13x + y = 13.30.
--------------------- 
A. Do you expect these lines to be parallel, perpendicular, or intersecting? Why?
Intersecting because the slopes are different: 2.09 vs. 1.13
----------------------------- 
B. Use the equations to determine if the lines are parallel. Are they? Why or why not?
No, because their slopes are not equal.
