R = 8 since 8 times 10 = 80
Answer: 
Step-by-step explanation:
To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.
[replace y with x and x with y]
[subtract both sides by 7/2]
[multiply both sides by -2/3]
[distribute]

Now, we have our inverse function.

5x+2y=3
-5x on both sides
2y=3-5x
divide by 2 on both sides
y=3/2-5/2x
rewrite in order (optional depending on teacher)
y=-5/2x+3/2
Stocks = 250
Net income = $4,000,000
Outstanding Shares = $1,000,000
Earnings Per Share = ?
Formula: EPS = Net Income / Outstanding Shares
Solution: EPS = Net Income / Outstanding Shares
= $4,000,000 / $1,000,000
= 4
Answer: Earnings Per Share = 4
