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

Answer:
I will use two different type of prisms:
Triangular prism:
The volume is equal to the area of the triangle multiplied by the heigt of the prism.
So:
300m^3 = A*H
Suppose that the triangle is a triangle rectangle with two equal cathetus of lenght L = 6m, then the area of the triangle is:
A = 6m*6m/2 = 18m^2
300m^3 = 18m^2*H
H = 300/18 m = 16.6m
So this prism is a triangular prism where the area of the triangular face is 18m^2 and the height is 16.6m
Rectangular prism:
Here the volume of the prism is:
V = W*H*L
Where W is the width, H is the heigth and L is the length.
300m = W*H*L
now we can assign values to two of the values and then find the other value.
Suppose W = 30m, H = 5m
300m^3 = 30m*5m*L = 150m^2*L
L = 300/150 m = 2m
So this prism has a width of 30m, a height of 5m and a length of 2m.
The answer is E. 16 divided by 10 is 1.6 and 10 divided by 10 is 1.
