The subscriber needs to use 363 minutes in a month in order for the second plan to be preferable
What should be sign between the equations for the second option to be better?
The sign between the equation of the first cell phone plan and the second phone plan must less than for the second option to yield more value
Let x be number of minutes of call
Total cost of first option=0.20x
Total cost of second option=39.95+0.09x
For the second option to be better, its value must be less than that of first option
39.95+0.09x<0.20x
39.95<0.20x-0.09x
39.95<0.11x
39.95/0.11<x
x>363

9x-y =8 re-arrange
y = 9x -8 slope , m = 9 parallel slope is the same = 9
point slope form thru point 4,4
y-4 = 9 ( x-4)
y-4 = 9x - 36
y = 9x -32
y - 9x = -32
9x-y = 32

You can divide this image into 2 different shapes and there are multiple ways to do this. I drew a line straight down from the side that has a length of 6 to divide the image into 2 rectangles
I now have a rectangle that has sides of 7 and 10 and a rectangle that has sides of 4 and 8
A=L*W so A=7*10 which is 70
A=L*W so A=4*8 which is 32
add these areas together to get 102 so "C" is the correct answer
