Tyler works in retail where she earns $10.50 per hour. She also earns $15 for every new credit account she gets customers to open and she gets a weekly stipend of $50 for clothing. Tyler knows her weekly earnings can be shown with the following expression:

10.50h + 15c + 50

Part A: Identify a coefficient, a variable, and a constant in this expression.
Part B: If Tyler works for 37 hours and opens 12 new credit accounts, how much does she earn? Show your work to receive full credit.
Part C: If Tyler gets a raise and begins earning $11.25 per hour, would the coefficient, variable, or constant in the expression change? Why?



Answer :

A:
Coefficient is a number multiplied by an unknown variable. Both 10.50 and 15 are coefficients

B:
You plug in the given values into the provided formula.
10.50(37) + 15(12) + 50
388.50 + 180 + 50 = 618.50

C:
Only the coefficient 10.50 would change to 11.25, because this is a representation of the dollar amount per hour that she works.
