A. A savings account’s balance.
You have 4 green picks and, after adding some orange picks, you know that every 2 picks from 3 are orange.
So, 1 green pick needs 2 orange picks, three in total. Since you have 4 green picks, then you will have in total 3·4=12 picks (4 green and 12-4=8 orange).
Answer: there are 12 picks in total.
5000:100=50. 50*4=200 5000-200=4800 do the same 5times more, always taking the last number, so now start with 4800:100....

Objective: Solving Piecewise Functions
Analyze the info in the graph.
We know that if x=1, the graph will coincide at 5.
If x is greater than 1, the answer will be x squared it answer so any positve interger greater than 1 the answer is that squared.
If x is less than 1, the answer will be double that x.
Let check the answer choices.
A is wrong because x is less than 1 so the answer should be 2(-2)=-4 not 4.
C is Wrong, since 5 is greater than 1, it must be 25 so 5^2=25
D and B are both right, 2 is greater than 1 so 2 squared =4 and Whenever x=1, it will equal 5.
No rounding is necessary to answer the question.
We can subtract the (linear) density of the second box from that of the first to see which box is heavier per unit height.
This value is obviously less than zero, so ...
... the box of magazines has the greater mass per unit height.
_____
The question didn't ask for the mass per height, and we didn't compute it. All we did was make a conversion to comparable units. The units we ended up with are mixed English and metric units, but that doesn't matter for the purpose of comparison.
Since all we're really interested in is <em>the sign of the difference</em> of mass/height, we don't even need to actually compute that difference. We just need to do enough computation to be able to tell whether the sign is positive or negative.
