The formula for the equation of y, the number of units sold as a function of x is y = 0.00625x + 250
<h3>How to illustrate the equation?</h3>
From the information given, when the company spends no money on advertising, it sells 250 units and for each additional $4000 spent, an additional 25 units are sold.
The formula for y will be:

Answer: 95.40
Step-by-step explanation:
7.95*12=95.40
So we have 52 horses. We know that 12 are white, so:
W : B - 12: x, where x is the unknown amount of horses.
52 - the twelve white horses = 40 other horses.
This means that there are 40 black horses, so the ration of W:B is 12:40. We can simplify this ratio.
The highest common factor of both numbers is 4, so the ratio can be divided by four, giving 3:10.
Therefore the ratio is 3:10.
