Can someone check my homework
marla has $95.50 in her savings account. she deposits $5 every week. her mother also deposits $20 into the account every time marla washes the car. her savings account balance can be shown with the following expression:
20c + 5w + 95.50
part a: identify a coefficient, a variable, and a constant in this expression. (3 points)
part b: if marla saves for 20 weeks and washes the car 5 times, how much will she have in her account? show your work to receive full credit. (4 points)
part c: if marla’s mom deposited $10 after each car wash, would the coefficient, variable, or constant in the expression change? why? (3 points)
part a - the coefficient would be 5, the variable is w, and the constant is 20
part b - 20(5) + 5(20) + 95.50 = money in account
100 + 100 + 95.50 = $295.05
$295,05
part c - the coefficient will change because the 20 represents the money after each car wash which is the coefficient
