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. (3 points)

Part B: If Anderson saves for 10 weeks and mows the lawn 2 times, how much will he have in his account? Show your work to receive full credit. (4 points)

Part C: If Anderson had $85 in his savings account, would the coefficient, variable, or constant in the expression change? Why? (3 points)

Answer 1

part A is W and M because those are the coefficient variable and constant.

Part B
`10*5=50 ~20*2=40 50+40=90`

part c it would change to 85

I really hope this helps you ^-^

Answer 2

Part A: 5 is the coefficient, w is the variable, 50 is the constant

Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140

Part C: the constant,50,would change and become 85. Hope this helps :)
