Mathematics

The sum of series is: -16

Step-by-step explanation:

First of all we have to breakdown the summation notation into terms

As the value of k is from 3 to 6

We will put k=3,4,5,6

So,

Putting k = 3

= -2(3)+5\\= -6+5\\=-1

Putting k =4

= -2(4)+5\\=-8+5\\=-3

Putting k = 5

=-2(5)+5\\=-10+5\\=-5

Putting k = 6

=-2(6)+5\\= -12+5\\=-7

The sum will be:

= = (-1) + (-3) + (-5) + (-7)\\= -1-3-5-7\\= -16

Hence,

The sum of series is: -16

A store has a 40% off sale oh headphones. With the discount the price of one pair of headphones is 36$ What is the original pric
Makovka662 [10]

Answer: $90

Step-by-step explanation:

Let the original cost be represented by x

From the question, it was given that the cost of headphones at 40% discount is $36

Thus, 40% discount = $36

100% = x

Then, convert to decimal

40% = 40/100 = 0.4

100% = 100/100 = 1

Therefore, 0.4 = $36

1 = $x

0.4x = $36

Divide both sides by 0.4

x = $36/0.4

x= $90

Original cost of the headphone was $90.

I hope this helps.
