Unformatted text preview: fee) was F(x) = 2.29x + 22.50 A. We sold 90 hats that year. How much was our total bill from Signature Shirts? (Yes, they do hats, too) F(90)=2.29(90)+22.50 F(90)=206.10+22.50 F (90)=228.60 B. How many hats would we have sold had we paid Signature Shirts $301.88? 301.88=2.29(x)+22.50 301.8822.50=2.29(x)+22.5022.50 279.38=2.29(x) 122=x Would have sold 122 hats C. What is our slope of this function? 2.29 D. What is our yintercept? (0,22.50) E. What does the slope represent? The amount of each hat 6. Our equation y = 2.09x + 15.50 represents our charge for hats. An estimate from a competing company, Lotsa Hats, was 2.09x + y = 13.30. A. Do you expect these lines to be parallel, perpendicular, or intersecting? Why? These lines are expected to be parallel. This is s because they have the same slope and different yintercepts. B. Use the equations to determine if the lines are parallel. Are they? Why or why not? Y=2.09x+15.50 2.09x+y =13.30 Y=2.09x+13.30 yintercept (0,15.50) yintercept (0,13.30)...
