For example: wages of less than $25 per hour have a $416 per month benefit paid, and wages between $25 and $29.99 per hour have a benefit of $624 per month benefit paid. The length of paid vacation (in weeks) is given in sheet vacation. The vacation length is based on the employment length. The spreadsheet named summary lists the name of each employee, the number of years they have been employed and to which craft skill they belong. The cell summary!B1 has been named hours and contains the number of hours per year each . employee is paid. Write an Excel formula in cell summary!D3, which can be copied down the column, to calculate the hourly wage for this person. Write an Excel formula in cell summary!E3, which can be copied down the column, to determine the total value of the benefits per year for this person. Note that the figures given in sheet benefits are per month. 3. Write an Excel formula in cell summary!F3, which can be copied down the column, to determine the total yearly value of the compensation including wages and benefits for this on.
