Question 85495
******
Sales.......Amt Recd
$50,000 ....$3000
$20,000 ....$1800..Subtracting
$30,000 ....$1200
For an increase in sale of 30,000 he gets a commn of 1200
which is 1200/30000=4%
Commission percent=4
So in 20,000 sales commission = 20000x0.04=800
Amount earned=1800
commission=800
So Basic Salary=1800-800=1000
Now the eqn for amount received by executive=1000+(total sale(S)x0.04)
The model is
A=0.04S+100
where A= amount Received by Executive, S=Total Sales
****
Using the model
For 85000$ sale,
we get A=(0.04x8500)+1000
=3400+1000
=4400
Answer $4400.
