Sheryl spends $9 dollars a week and $30 dollars a month on dry cleaning

$9/week = approx. $36 per month

To find out how much Sheryl spends on dry cleaning in total (weekly and monthly), we can add the weekly and monthly expenses.

Weekly expenses: $9
Monthly expenses: $30

To convert the monthly expense to weekly, we need to divide it by the number of weeks in a month. On average, there are 4.33 weeks in a month.

Monthly expense / Number of weeks in a month = $30 / 4.33 = $6.93 (rounded to the nearest cent)

Now we can add the weekly and monthly expenses to calculate the total amount Sheryl spends on dry cleaning.

Total dry cleaning expenses = Weekly expenses + Monthly expenses
= $9 + $6.93
= $15.93

Therefore, Sheryl spends a total of $15.93 on dry cleaning.
