We have been given that Ralph earns $72,000 annually as an architect and is paid semimonthly.
Semimonthly means twice in a month. There are 12 months in a year.
Therefore, in a year Ralph gets
![12\times 2 = 24 \text{ checks}](https://tex.z-dn.net/?f=12%5Ctimes%202%20%3D%2024%20%5Ctext%7B%20checks%7D)
Now, Alice also earns $72,000 but she is paid biweekly.
Biweekly means twice a week. There are 52 weeks in a year.
Therefore, in a year Alice gets
![52\times 2 = 104 \text{ checks}](https://tex.z-dn.net/?f=52%5Ctimes%202%20%3D%20104%20%5Ctext%7B%20checks%7D)
The difference in the number of checks is 104 - 24 = 80
Thus, Alice receives 80 more checks in a year when compared to Ralph.
