Answer:
<h2>
<em>0</em><em>.</em><em>9</em><em>%</em></h2>
<em>Solution,</em>
<em>Yesterday's</em><em> </em><em>price=</em><em>$</em><em>9</em><em>.</em><em>6</em><em>2</em>
<em>Today's </em><em>price=</em><em>$</em><em>9</em><em>.</em><em>7</em><em>1</em>
<em>Price </em><em>increased=</em><em>9</em><em>.</em><em>7</em><em>1</em><em>-</em><em>9</em><em>.</em><em>6</em><em>2</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>$</em><em>0</em><em>.</em><em>0</em><em>9</em>
<em>increased </em><em>percent</em>
<em>=</em><em>increased </em><em>amount/</em><em>old </em><em>amount*</em><em>100</em>
<em>=</em><em>0</em><em>.</em><em>0</em><em>9</em><em>/</em><em>9</em><em>.</em><em>6</em><em>2</em><em>*</em><em>100</em>
<em>=</em><em>0</em><em>.</em><em>9</em><em>%</em>

Answer:
The correct answer is last option 3√2 units
Step-by-step explanation:
From the figure we can see that two small right angled triangle.
These two triangle combined to form a large right angled triangle.
<u>To find the value of x</u>
Consider the small triangle with hypotenuse x and one side 3 units.
The angles of this triangle be 45°, 45° and 90°, then the sides are in the ratio 1 : 1 : √2
Therefore we can write,
3 : 3 : x = 1 : 1 : √2
x = 3√2
The correct answer is last option 3√2 units
The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.
Given that:-
Price of the laptop after 1 year = $ 400.
Inflation rate = 2.5 %
We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.
Let the price he had to pay be x.
Hence, we can write,
x + (x*(2.5)*1)/100 = 400
x(1 + 1/40) = 400
x(41/40) = 400
x = 400*40/41 = $ 16000/41 = $ 390.24.
