Answer:
Step-by-step explanation:
It may be easier for you to see what's happening here if you'd write the given 1/4 = 3/5s as:
1 3
---- = -----
4 5s
Cross multiplying results in 5s = 12, so that s = 12/5.
If, however, you actually meant 1/4 = (3/5)s, then the solution is quite different:
1/4 = 3/5s => 1/4 = 3s/5, or
1 3s
---- = -----
4 5
Cross multiplication results in 12s = 5, or s = 5/12.
Which did you mean, 1/4 = 3 / (5s) or 1/4 = 3s / 5?
This goes to show how important it is to use parentheses to remove any ambiguity.
0.25 x 40,000 = - $10,000 ( lose )
0.35 x 0 = 0 ( break even )
0.4 x 30,000 = +$12,000 ( profit )
$12,000 - $10,0000 = $2,000
Answer:
A ) The expected value is $2,000, so the company should proceed with a project.
Answer:
Yes, because the slopes of the equations are different so the system of equations will have one solution.
