Question

Ellen has $75 in her savings account. She deposits $25 every week. Her father also deposits $35 into the account every time Ellen mows the lawn. Her savings account balance can be shown with the following expression:

75 + 25w + 35m

Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points)

Part B: If Ellen saves for 8 weeks and mows the lawn 2 times, how much will she have in her account? Show your work to receive full credit. (4 points)

Part C: If Ellen had $95 in her savings account, would the coefficient, variable, or constant in the expression change? Why? (3 points)

Answer 1

coefficients are 25 and 35
variables are w and m
constant is 75
$345
constant would change since the constant in this situation is the amount of money she has in her savings account
