The finance Charge would be $140. you would multiply 18 by 80 and then add the 130 and take that number and subtract the 1,430
Relationship 1: y1 = x + 3
Relationship 2: y2 = 3x^2
Relationship 3: y3 = 3^x
You would want to go by reverse order of operations. This is a one step equation. You subtract 2 on both sides, in which you will get: -14 = k.
