<em>The question is incomplete as the dimension of the phone was not given.</em>
<em>However, the following explanation will guide you</em>
Given

Required
Determine the Height
Volume is calculated as thus;

Substitute 75 for Volume

Divide through by Area

<em>The above represent the equation to solve for Height</em>
<em>To solve for height, we need the dimension of the phone or the area.</em>
Take for instance; the length and width of the phone is 5 by 5 inches;
The height would be:



I think the answer is D) 24/25.
Again sorry if its wrong!!
They probably want 880 pesos, since they asked you do intermediate rounding
but a more accurate answer would be
883.20 pesos
To combine the functions, you'd substitute in 2.76r for y in 0.16y. This would give you 0.16(2.76r), which simplifies to 0.4416r, but they want you round this to the nearest hundredth, so its really 0.44r. Substitute in the 2000 for r and you get 0.44 * 2000 which is 880 pesos
It will take him 240 min and if u convert that it will take him 4 hours
Answer:
