Question

Jamar is finding the selling price of a pair of $40 skates with 30% markup. Find his mistake and correct it.

Answer 1

that is a letter s BTW...try cross multiplying this...

`100x = 1200 \\ / 100 = / 100 \\ x = 12`

Answer 2

The selling price will be $52 dollars.

Explanation:

If the skates have 30% markup we need to ADD up this percentage to the original selling price.

First we will use a rule of three to find the 30% of 40.

$40 -- 100%

x -- 30%

`x=(40)(30)/100\\x=12`

Now we add up the $12 to the $40 skates.

The selling price would be 40 +12 = 52 dollars.
