Final answer:
To write a linear model relating total monthly wages (W) to sales (S), add the fixed salary to the commission, where the commission is 5% of the total monthly sales.
Step-by-step explanation:
To write a linear model relating total monthly wages (W) to sales (S), we need to consider two components: the fixed salary and the commission. The fixed salary can be represented by the constant term and the commission can be represented by the coefficient of the sales variable.
Let's assume the total monthly sales is 'S'.
The fixed salary is $1850.
The commission is 5% of the total monthly sales, which can be calculated as 0.05 * S.
Therefore, the linear model that relates total monthly wages W to sales S is: W = 1850 + 0.05S.
