Answer:
see below
Step-by-step explanation:
x - 2/5= 7
Add 2/5 to each side
x - 2/5 + 2/5 = 7+2/5
x = 7 2/5
or if
( x-2) /5 = 7
Multiply each side by 5
(x-2) /5 *5 = 7*5
x-2 = 35
Add 2 to each side
x-2+2 = 35+2
x = 37
We conclude that the profit if the company produces 10 units is 1,040 dollars.

How to find the profit?</h3>
The profit is defined as the difference between the revenue and the costs.
In this case, we know that the revenue and costs are defined by:
R(x) = 200x - 5x^2
C(x) = 360 + 6x
Then the profit equation is:
P(x) = R(x) - C(x).
P(x) = 200x - 5x^2 - (360 + 6x)
P(x) = -5x^2 + 194x - 360
Now we want to find the profit when x = 10, then we will get:
p(10) = -5*10^2 + 194*10 - 360 = 1,040
We conclude that the profit if the company produces 10 units is 1,040 dollars.

If 93% of the bar is silver, then the bar is 0.93*8.15 ounces of silver. Solving that makes there 7.58ish ounces of silver in the bar
There are several information's of immense importance already given in the question. based on those given information's the answer to the question can be easily derived.
Total number of students = 840
Then
Number of students going to the concert = (7/12) * 840
= 7 * 70
= 490 So
Number of students not going to the spring concert = 840 - 490
= 350
So 350 students did not go to the spring concert.I hope the procedure is clear enough for you to understand. You can always use this procedure for solving similar problems in future without requiring any help from outside.
