In a week, Tracy earns 12.45 less than twice the amount Kayla earns. Tracy earns $102.45. Write and solve an algebraic equation to show how to find the amount Kayla earned. 

 

 

 

PLEASE help and walk me through it!!

Answer 1

Amount Kayla earns = x

So Tracy earn =2x-12.45

 

2x - 12.45 = 102.45

2x=114.9

x =57.45

 

so Kayla earns = $57.45
