Given :
Weekly salary , S = $150.
Commission per car , C = $325.
To Find :
The the equation that models the weekly salary of a car salesman.
Solution :
We know it is a quadratic equation :
Let , the equation is , y = mx + c
Here, x is number of car sold in a week.
For x = 0 ( He will not get commission)
So , Salary is $150 = c .
For x = 1
Salary is $( 150 + 325 ) = $475 = m(1) + c
Therefore , m = $325 and c = $150.
Required linear equation is y = 325x + 150.
Hence, this is the required solution.
