Millie has $83.50 in her savings account she deposited $15 every week or mother also deposit $10 into the account every time lily washes her car her savings account balance commission with the following expression 10 c +15 w +83.50

In the problem, it was being given that the expression 10C + 15W +83.50 will be used and can be used when computing the total amount was able to save. It has an initial value of $83.50, then every time Millie cleans the car, she will be paid an amount of $10 and put this amount on her savings. It was also mentioned that Millie deposited an amount of $15 weekly and W is the number of total weeks. For example, Millie deposited for 4 weeks already so it means we have $15 times 4. If she cleaned the car 5 times already, it means we have $10 times 5.So the total savings is shown below:
Savings = 10*5 + 15*4 + 83.5
Savings = $193.5
