Answer:
The answer would be B
Step-by-step explanation:
The reason that we know this is because the line is falling and because it is a solid line then we know that it is ≥ and not just >. the solid line already gets rid of C and D. A is a positive number which would cause the line to go the opposite direction. Therefore B is your only answer left.
So..hmm check the picture below
the pyramid is really just 4 triangles and 1 square at the bottom, all stacked up to each other at the edges
get the area of the square bottom, is just a 6x6 square, thus the name of the pyramid
and get the area of each triangle, notice the base is 6, the altitude or height is 9
and add them all up, that's the surface area of the pyramid
Figure out the difference between the two options. $60 minus $25 is $35, so you can use $35 worth of 10 cent minutes each day to have the same cost.
I worked that out to be 350 minutes per day. Then I mulitplied it by three to make three days, and got 1050 minutes. Dividing that by 60 gave me the number of hours I'd have to use: 7.5 hours.
So that's 7.5 hours to break even. If I use more time than that it will be cheaper to use the second option.
