Part C: If Corinne gets a raise and begins earning $9 per hour, would the coefficient, variable, or constant in the equation change? Why?

constants -- just numbers....no letters.......ex: 5,6,7,8,9 variable -- the letters.....ex: n,m,x,y, coefficient -- a number multiplied by a letter (variable)....ex: 4n,3y,8z ======================== if she earned 300 and worked for 25 hrs... so sub in 25 for h and 300 for s and solve... 7.50(25) + 0.20(300) + 40 = money earned for the week. (you can do the math) ======================= if she earned 9.00h instead of 7.50h....so the item that will change is the number multiplied by the variable....and what is that called ?
