Answer:
The economic concept of scarcity.
Explanation:
In economics, <em>scarcity</em><em> </em>represents the phenomenon of <em>limitless</em> <em>wants</em> suppressed by <em>limited</em><em> </em><em>resources</em>.
In this case, Allie feels she needs $90 shoes while she has not got the resources required to buy them.
This typical economic problem can be solved by moderating one's wants and clearly identifying what is priority from what is not, then intelligently making decisions on what available resources should be spent.

first answer looks best
Explanation:
the government wanted to eliminate monopolies in business so they tried to encourage competition in the marketplace
Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.
Hello,
The answer to #18 will be 4 since for every x-value, the y-value increases by 0.5. It's just that they skip some of the x-values tricking you.
So, let's use the first column set of answers to find the price for 4 tickets WITHOUT the service fee. If the service fee is $8.50, we need to subtract that from the total amount $56.50 to find out the prices for the tickets without the service fee: $48.00
Divide that by 4 so you can find out the number for just one ticket and you'll find that it costs $12.00 for a ticket without the service fee.
Now finding how much a single ticket costs, let's plug it in:
9 x $12.00 = $108.00 AND now you have to add the $8.50 as the service fee:
$108.00 + $8.50 = $116.50 dollars
Hope this helps!
