This question is the on I need help with

allsm [11]

let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.

likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.

197 - 122 = 75 oz

and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.

A department store buys 100 shirts at a cost of $2 comma 700 and sells them at a selling price of $30 each. Find the percent m

Zinaida [17]

The percent markup is 11.11 %

Solution:

Given that, the store buys 100 shirts at a cost of $ 2700

Let us find the cost of 1 shirt

$\text{cost of 1 shirt } = \frac{2700}{100} = 27$

The store sells them at $ 30 each

Therefore,

Cost price of 1 shirt = $ 27

Selling price of 1 shirt = $ 30

Markup price = Selling price - Cost price

Markup price = 30 - 27

Markup price = 3

Thus markup price is $ 3

The percent markup is given as:

$\text{Percent markup } = \dfrac{\text{Mark up}}{\text{Cost price}}\times100\\\\\text{Percent markup } = \frac{3}{27} \times 100\\\\\text{Percent markup } = 11.11$

Thus the percent markup is 11.11 %
