He wants to be intimate how much money atomic number 2'll earn if he works all day from Feb 21, 2022 done May 1, 2022. Rather of manually calculating this timeframe (account statement for number of days per calendar month, Intercalary year, etc.), you can use Surpass to quickly solve this problem.

The formula for this calculation is simple: Just subtract the end date from the originate in engagement:

=SUM(B1-A1). The result is 70 years. Now add Magnum's daily rate to the end of this formula:

=SUM(B1-A1)*200 and you get the solvent in one easy formula: $14,000.00. That whole works resolute about $25 an hour—lousy payoff even for the 1980s.
