Step-by-step explanation:

arithmetic progression

even numbers between 1001 and 10000

1002,1004,.......9998

Tn=a+(n-1)d

Tn = 9998 last term in the progression of even numbers

a = 1002 first term

d = 2 distance

9998=1002+(n-1)(2)

8996=2n-2

8998=2n

n = 4499 the number of terms

sum = n/2 (a+Tn) = 4499/2(1002+9998)

= (4499/2)(11000) = 24744500

Logic:

notice what happens when you add the first and last terms

1002+9998=11000

1004+9996=11000

The price of a TV after a 20% discount is $620, what was the price before the discount?​
makvit [3.9K]

Answer:

The original prince is: $775            

Step-by-step explanation:

  • As the discount is 20%.

As we know that

  • 100% - 20%  = 80% = 80/100 = 0.8

The price after 20% discount = Discounted price = $620

We have to find the original price before the discount.

using the formula

(Discounted price) = (100 percent - discount percent) x (original price)

          $620            = (100% - 20%) x (original price)

          $620            = (80%) x (original price)

          $620             = (80/100) x (original price)

          $620              = (0.8) x (original price)

so

original price = $620/0.8

                      = $775

Therefore, the original prince is: $775
