The percent gain is 52.1%
Step-by-step explanation:
Given
Purchase price of one share = $22.75
Sale price of one share = $34.60
Total shares = 400
So,
Total purchase price of shares = 22.75*400 = $9100
Total sale price of shares = 34.60*400 = $13840
Total capital gain:
Percent capital gain is given by:
Rounding off to nearest tenth

Let A and B represent the number of hours that plans A and B last, respectively. Then the problem statement tells you
7A +9B = 12
5A +3B = 6
There are many ways this set of equations can be solved. I find it fairly simple to use a graphing calculator. The one shown tells me the workouts are each 3/4 of an hour.
Plan A lasts 45 minutes (3/4 hour)
Plan B lasts 45 minutes (3/4 hour)
7A +9B = 12
5A +3B = 6

Graph using slope and the y intercept
So y=x+5
You would plot the y intercept (0,5) and then go up 1 and to the right 1
The next graph plot y intercept (0,-1) and then go down 2 and to the right 1
And should look like the image
And your solution should be (-2,3) which is option c
