Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowa

Fudgin [204]

7.50h + 0.20s + 40

variable : a letter subbed in for an unknown number : s and h
coefficient : the number multiplied by the variable : 7.50 and 0.20
constant : just a lone number, no variable attached : 40

Corrine works for 25 hrs and sells 300......h = 25, s = 300
7.50h + 0.20s + 40
7.50(25) + 0.20(300) + 40 =
187.50 + 60 + 40 =
287.50 <===

if she gets a raise and earns 9 per hr...
the coefficient would change from 7.50 per hr to 9.00 per hr. because her pay rate has changed.
the new equation would then be : 9h + 0.20s + 40
