Batteries which normally sell for $1.89 a pack are on sale for $3.40 for two packs. Approximately what percentage markdown does this represent per pack?

Question

I keep getting 6% and that's not an answer...

Answer 1

Hi Danielle,

 

"Percentage markdown" is the change in price divided by the original price, expressed as a percent. We can write this as

 

  markdown = (change in price / original price) * 100

 

where the *100 makes it percent.

 

For our batteries, the original price is $1.89 per pack. On sale, $3.40 for two packs, so $1.70 per pack. Therefore,

 

  markdown = [(1.89 - 1.70) / 1.89] * 100 = [0.19 / 1.89] * 100

 

I'll leave it to you to finish the math! But you are correct, it is not 6%, it's higher than that.

Answer 2

$1.89 is the regular price

$3.40/2=$1.70 per pack on sale

you are going from $1.89 to $1.70

$1.89-$1.70=$0.19

$0.19/$1.89=19/189=0.100529

0.100529=10.0529 % decrease (10.0529 % markdown)

Answer 3

The regular price for 2 packs is:

 

2*($1.89) = $3.78 

 

The savings by purchasing two packs at the sale price of $3.40 is:

 

$3.78 - $3.40 = $0.38

 

The markdown is:

 

($3.78)x(Markdown %) = $0.38

 

Markdown % = $0.38/$3.78 = 0.10053 ≅ 10%
