Task $2$ Computing the rental period

$$ Insert a new column F and name it $$Rental Period $($Weeks$).$

$$ Create a formula that correctly computes the number of weeks that cabin was rented.

$$ Hint: remember that Excel stores dates as numbers

$$ Copy your formula down to the bottom of the data

WARNING: Be careful to copy your formula only to the bottom of the actual

data, not all the way to the bottom of the sheet at row $1,048,576.$ Creating a

million rows of useless formulas will make your spreadsheet become really slow!

$$ Hint: remember that you can use keyboard shortcuts to rapidly move up and

down enormous ranges of cells.
