1, Might not be precise
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes.
This is just from the top of my head.
Blake saved 
Option - A
<u>SOLUTION:
</u>
Given, Blake and James are planning to go on a trip.
Blake already has some money saved.
Let the amount saved by Blake be 
.
She earns 
more by working overtime.
Then, total amount by Blake 
James has 
more than 4 times the amount of money that Blake has saved.
Then, total amount by James will be 
If they have 
in all, we have to find how much money had Blake originally saved
Now, total amount = 
So you would use a frequency table when they are asking for how many times does this come in to the play. For example , let's say there was a play and 2 different characters we're in it the cat came out 3 times and the the dog came out 5 times. Which character came out more times.
Corner points in this graph are: ( 0,0 ) ( 0,8 ) ( 5,6 ) and ( 8, 0 ).
If we plug those values in : P = 2 x + 3 y
P ( 0,0 )= 0
P ( 0,8 ) = 2 * 0 + 3 * 8 = 24
P ( 6 , 5 ) = 2 * 6 + 3 * 5 = 12 + 15 = 27
P ( 8 , 0 ) = 2 * 8 + 3 * 0 = 16
The maximum value is:
P max ( 6 , 5 ) = 27
