Answer:
[tex](31x)\times 16\%[/tex]

x dollars is charged on every job posting on website.
Now, lets find the discount on 31 job posting.
∴ Total cost on 31 job posting = [tex]\textrm{charges for one job posting}\times \textrm{Total number of job posting}[/tex]
⇒ Total cost on 31 job posting= [tex]x\times 31= \$ 31x[/tex]
As we know 16% discount been offered for 20 or more job posting
∴ Discount offered on 31 job posting = [tex]31x\times 16\%[/tex]
Discount offered by JobFind to the employer is [tex](31x)\times 16\%[/tex]
