[tex]Earnings = 300 + 5\% * 2175[/tex]
[tex]Earnings = 300 + 108.75[/tex]
[tex]Earnings = 308.75[/tex]
Solving (b): Sales of $x in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * x[/tex]
Convert percent to decimal
[tex]Earnings = 300 + 0.05 * x[/tex]
[tex]Earnings = 300 + 0.05x[/tex]
