If Frank has an yearly salary of $52,200 and gets a raise of 8%, we should just calculate 8% of this value and add to his salary. To calculate 8% we just need to multiply by 8 and divide by 100, in other words, multiply by 0.08.
[tex]52200\times\frac{8}{100}=4176[/tex]Adding his raise to his yearly salary we have:
[tex]52200+4176=56376[/tex]Frank now receives $56,376 a year.
