Given:
Selling price of a fan = Rs.4700
Loss percent = 6%
To find:
The price at which he must sell it to gain 6 percentage.
Solution:
Let x be the cost price of the fan.
Loss percent = 6%
Selling price = Cost price - 6% of cost price
Selling price of a fan = Rs.4700
So, the cost price of the fan is Rs.5000.
Now, he need to sell this fan in 6% gain.
Selling price = Cost price + 6% of cost price
Therefore, he must sell it for Rs.5300 to gain 6 percentage.
Lets write the information as an equation, and name x the number unknown:
(x + 4)^2 = 36
that is:
the sum of a number and 4: (x + 4)
then, the square of <span>the sum of a number and 4: (x + 4)^2
so we have:
</span>(x + 4)^2<span> = 36
</span>to solve we calculate square root to both sides of the equation:
(x + 4)<span> = 6
</span>then we solve for x:
x = 6 - 4
x = 2
so the unknown number is 2
Answer:
12
Step-by-step explanation:
-3 * 2 is -6
-6 * -2 is 12
because a negative times a negative is positive
Let one angle be x
Let another angle be 17x
17x+x = 90
18x = 90
x = 90/18 = 5
one angle = x = 5
another angle = 17x =17*5 = 85

The function would have to be the total cost as a function of the number of tickets bought. When you write that in functional notation, that would be C(m). Now, the cost must include the fixed rate of $25 plus a variable rate of $6 per ticket. The function would be,
<em>C(m) = 25 + 6m</em>
