Find the markup and the selling price of the following item. round answers to the nearest cent. a skateboard costing $39.00 marked up 40% on cost.

markup =

selling price =

The markup price of the item is  1560 cents  and the selling price of the skateboard is 5460 cents .

Step-by-step explanation:

As given

A skateboard costing $39.00 marked up 40% on cost.

40% is written in the decimal form .

= 0.40

Markup price = 0.40 ×  Cost of the skateboard

                      = 0.40 × 39

                      = $15.6

As

1 dollar = 100 cents

Now convert 15.6 dollars into cents .

$15.6 = 15.6 × 100 cents

         = 1560 cents

Thus markup price is 1560 cents .

Selling price of the items = Original cost of the skateboard + Markup price  

                                          = $39 + $15.6

                                          = $ 54.6

As

1 dollar = 100 cents

Now convert 54.6 dollars into cents .

$54.6 = 54.6 × 100 cents

         = 5460 cents

Thus selling price of the skateboard is 5460 cents .

Therefore the markup price of the item is  1560 cents  and the selling price of the skateboard is 5460 cents .

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
