Answer:
$12
Step-by-step explanation:
The answer is 12 because 20% of 10 is 2 and 10 plus 2 is 12
Answer:
120x + $20 = $200
x = $1,5
Step-by-step explanation:
We need to find out the price of each candy bar we sold. Let's define x, our variable, as this price that we need to find out.
We know that we met the goal of raising $200 by selling candy bars and with the $20 donation. We need to have this in mind when we write the equation.
Therefore, if we multiply the 120 candy bars we sold by the unit price and we add the $20, it has to be equal to $200.
In math language, that is
120x + $20 = $200
Let's solve it to find out the x. First we subtract $20 from both sides:
120x + $20 - $20 = $200 - $20
120x = $180
Now we divide by 120:
120x/120 = $180/120
x = $1,5
We sold the candy bars for $1,5 each.
We can also interpret that we met the goal and exceed it. The calculation is the same but we need to change the equal sign with a greater sign, because the amount we raise was greater than $200. That is
120x + $20 > $200
With the same calculations, we will get
x > $1,5
That means that the candy bars were sold for more than $1,5 each.
Actually Welcome to the concept of Radioactive decay.
N(t) = 72(1/2)^22/11
==> N(t) = 72 (1/2)^2
==> N(t) = 72/4
==> N(t) = 18 grams.
So the remaining would be 18 grams.
The decreasing of the prices and increasing of buying are correlated with the human behavior.
<h3>What is a Demand Graph ?</h3>
Demand graph is the curve in the study of economics which tells us about the number of units purchased or the demand of the product with respect to the price.
The demand line slopes downward means the price is decreasing and more people are buying it.
The increase in the buying of the goods on decreasing prices is affected by human behavior as when the price decrease , the middle class people have a tendency to buy more quantity and
even there is need to satisfy unsatisfied wants , If a product was costlier before and the prices have decrease then to satisfy the wants , the people buy it ,
Hence decreasing of the prices and increasing of buying are correlated with the human behavior.
