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?

A. coefficient : 5wthe 5 is the coefficient
     variable : 20mthe 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 changebecause u are starting with 85 instead of 50

Replace ∆ with a variable and solve.

Also it's no solution
