Question

A pharmaceutical salesperson receives a monthly salary of $4700 plus a commission of 2% of sales. Write a linear equation for the salesperson's monthly wage W in terms of monthly sales S.

Answer 1

`W= 4700+0.02S`

Explanation:

Given that

W is the monthly wage

S is the monthly sales

According to the problem statement, salesperson receives a monthly salary of $4700 (sales or no sales made he/she gets that amount)

Also plus 2% commission of sales made for the month added to the wage

we can model his/her wage as follows

`W= 4700+ (2/100)S\\\\ W= 4700+0.02S`

Hence the model for the monthly wage is
`W= 4700+0.02S`
