Question

Anderson has $50 in his savings account. He deposits $5 every week. His father also deposits $20 into the account every time Anderson mows the lawn. His savings account balance can be shown with the following expression: 50 + 5w + 20m Part A: Identify a coefficient, a variable, and a constant in this expression. Part B: If Anderson saves for 10 weeks and mows the lawn 2 times, how much will he have in his account? Part C: If Anderson had $85 in his savings account, would the coefficient, variable, or constant in the expression change? Why?

Answer 1

A. coefficient : 5w....the 5 is the coefficient
variable : 20m....the variable is m
constant : 50

B. saves for 10 weeks, mows 2 times....
50 + 5(10) + 20(2) = 50 + 50 + 40 = $ 140 <==

C. the constant would change....because u are starting with 85 instead of 50
