Answer:
The final cost for the service that offers the better deal is $56 per month, in total for the whole year it's $672.
The cost for the one that offers the worse deal is $65 per month.
Step-by-step explanation:
All we need to do is multiply the amount of money by the number of employees.
So:
20 × $2.80 = $56
(Calculations for worse deal)
20 × $3.25 = $65
