kayla worked 3x+6 hours this week she earns x-2 dollars per hour

Question

Write a polynomial expression that represents the amount Kayla earned this week

calculate her pay for the week if x = 11

Answer 1

Pay = (Wage per hour)(number of hours)

 

Pay = (x - 2)(3x + 6)

 

Pay = 3x² + 6x - 6x -12

 

or

 

Pay = 3x² - 12

 

If x = 11, Pay = (3)(11²) - 12 = = (3)(121) - 12 =  $351
