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 allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression: 7.50h + 0.20s + 40 Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points) Part B: If Corinne works for 25 hours and sells $300 in magazines, how much does she earn for the week? Show your work to receive full credit. (4 points)

    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 ?
