Given
Triangle is dilated by a factor of
i.e. each side multiplies to 0.25.
Side E'F' becomes 0.25 times the original length

The commission is 20% of sales, the basic salary is $200 and the equation is y = 0.2x + 200
<h3>What is an
equation?</h3>
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

This is Pythagorean's Theorem, with one leg being 10 and the hypotenuse being 16. Using those values in the theorem looks like this:

and

and

so

Take the square root of both sides to find that b = 12.5
