For this problem you need to create a RATIO, dont worry, it's not as hard as it sounds!
The ratio should look like this: 665/7
Now divide to get your answer!
You should get 95 points!
Hope this helps!
Comment if you have questions!!!
X/4 - 4 =18
This is the correct equation and if you solve it it X=88
The cost of the premium - $16,000 (40 x $400)
The cost of coverage - $150,000
The cost of the coverage is more
Expression A: S= 100+ 100(0.15y) y=Commission
Expression B: S= 150+ 150(0.10y)
Now to get Part B done. Plug in numbers for Y and use the results as the sales continue to increases. For example, start with 5 sales, then go to 10 then 15, and so on and so fourth. Hope I was able help you understand the question a little bit more! :)
