To calculate the total cost including tax, we first need to find how much the sales tax will be on the treadmill.
Sales tax = 5% of $661
Sales tax = 0.05 * $661
Sales tax = $33.05
Now, we can find the total cost including tax by adding the price of the treadmill and the sales tax:
Total cost = $661 + $33.05
Total cost = $694.05
Therefore, the total cost including tax will be $694.05.
