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.
So would the coefficient be 5 and would the x be the variable. I think the constant would be 95.50

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.

Part C: If Marla’s mom deposited $10 after each car wash, would the coefficient, variable, or constant in the expression change? Why?

Part A: You've correctly identified the coefficient as 5, the variable as w, and the constant as 95.50. Well done!

Part B: To find out how much Marla will have in her account after 20 weeks and 5 car washes, we can substitute the values into the expression and calculate it.

20c + 5w + 95.50

Since Marla's mom deposited $20 after each car wash, we can multiply the coefficient (c) by 20 times the number of car washes (5). Therefore, c = 5.

Now let's substitute the values:

20(5) + 5(20) + 95.50
= 100 + 100 + 95.50
= 295.50

Therefore, after 20 weeks and 5 car washes, Marla will have $295.50 in her savings account.

Part C: If Marla's mom deposited $10 after each car wash instead of $20, the coefficient would change. The coefficient represents the value of each car wash, so it would be reduced to 10 instead of 20. The expression would then be:

10c + 5w + 95.50

The variable (w) and the constant (95.50) would remain the same because they are independent of Marla's mom's deposit amount.
