Each Saturday, a store reduces the price of any unsold item by

10%. If an item was priced at $80, on Saturday of the first week it

is marked down to $72. At the end of the second week, it drops

to $64.80, and at the end of the third week the price is decreased

to $58.32. If this continues for 10 weeks, what should be the

selling price for an item that was originally priced at $80?

a-$27.89

b-$30.99

c-$52.11

d-$8.00

The correct option is a-$27.89

The selling price for an item would be $27.89 after the 10th week which was originally priced at $80.

Step-by-step explanation:

Each week, a store reduces the price of any unsold item by 10%

If this continues for 10 weeks, what should be the selling price for an item that was originally priced at $80?

The reduced price of the unsold item is given by

Initial price × (1 – discount) ⁿ

Where discount is 0.10 and n is the week number

After 1st week:

$80(1 - 0.10)¹

$80(0.90)¹

$72

After 2nd week:

$80(1 - 0.10)²

$80(0.90)²

$64.80

After 3rd week:

$80(1 - 0.10)³

$80(0.90)³

$58.32

Similarly, we can find the price of the unsold item for the 10th week by substituting n = 10

After 10th week:

$80(1 - 0.10)¹⁰

$80(0.90)¹⁰

$27.89

Therefore, the selling price for an item would be $27.89 after the 10th week which was originally priced at $80.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
