Determine his basic salary and his commission percentage and express the relationship between sales and salary in the form of an equation.​

Answer 1

The commission is 20% of sales, the basic salary is $200 and the equation is y = 0.2x + 200

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the total sales for x weekly sales, m represent the commision and b represent the basic salary. Hence:

400 = 1000m + b  (1)

Also:

300 = 500m + b  (2)

Hence:

m = 0.2 = 20%, b = $200

The commission is 20% of sales, the basic salary is $200 and the equation is y = 0.2x + 200
