This month the salesperson had $8,000 in sales. What amount of commission, in dollars, did she earn?

Part A

Commission total = Commission 1+ Commission 2

Where

Commision 1 = 5% of first 45000

Commission 2 = 7.5% of the amount left after $5000 is subtracted

thus

Commision 1 = $5000x.05

                     = $250

Commission 2= $3000 x.075

                       = $225

Commission total = $250+$225

                             = $475

The total commission she earned is $475ion

Part B.

Total sales = Sales with 5% commission+Sales with 7.5% commission

Sales with 5%commission= $5000

Commision At 7.5% = Total commision -Commission with 5%

                          =    $1375-$250

             Sales x.075=  $1125

             Sales with 7.5% commision = $15000

Total sales = $5000+$15000

Total sales = $20000

Total sales for commission of $1375 is $20000
