Craig runs a clothing store. he has decided to apply a markdown of 30% to one item in order to draw customers into the store, and he will apply a markup of 25% to three different items, which he hopes the customers will purchase after purchasing the marked-down item. he has chosen four candidates for this process: a leather jacket with an initial cost of $112.75, a blazer with an initial cost of $76.85, a pair of boots with an initial cost of $134.50, and a wristwatch with an initial price of $89.65. after applying the changes, the total cost of purchasing one of each item is $29.46 more than it was before applying the changes. which item was marked down?

The solution to this problem is trial and error. You know that if you have a total cost of purchasing one of each item, it will be $29.46 more than the total cost.

Add the three items before markup or markdown = $112.75+$76.85+$134.50+$89.65 = $423.75

So, apply markup to the leather jacket, blazer and wristwatch and apply mark down to the boots and you will get.

$112.75(1.25) + $76.85(1.25) + $134.50(1-0.30) + $89.65(1.25) = $443.21

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the answer would be c
