Given :
Two companies offer jane sales position. Company a pays $3,000 per month plus $250 per car sold.. Company B pays 2,500 per month plus $350 per car sold.
To Find :
Which equation could be used to determine the number of cars sold in a month, x, that would result in the same total income from each company.
Solution :
Let, x car are sold for same income.
Mathematical equation of company one :

Mathematical equation of company two :

For same income :

So, for same total income from each company the number of cars sold in a month should be 5.
Hence, this is the required solution.
Answer:
<h2>2. Because 25<12, this equation can not be true.</h2>
Step-by-step explanation:
I just solved the equation and 1/2 + 3/8 = 7/8 or 87.5%.
4/10 equals 40%.
Since these two do not sync up, the equation must be false and 2 is the only answer saying the equation is false.
I'm always happy to help :)
We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc. For this type of problem you use the "n choose k" formula...
n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..
In this case:
20!/(10!(20-10)!)
20!/(10!*10!)
