Tcecarenko [31]

Answer:

The markup rate is 144% .

Step-by-step explanation:

Formula

$Mark\ up\ percentage = \frac{(Selling\ price-Cost\ price)\times 100}{Cost\ price}$

As given

Clara Schumann is buying bagels for her coworkers, She buys a dozen bagels priced at $5.49 a dozen.

i.e

Selling price of a dozen bagels is $5.49 .

The bakery's cost for making the bagels is $2.25 per dozen.

i.e

Cost price of a dozen bagels is $2.25 .

Putting all the values in the formula

$Mark\ up\ percentage = \frac{(5.49-2.25)\times 100}{2.25}$

$Mark\ up\ percentage = \frac{3.24\times 100}{2.25}$

$Mark\ up\ percentage = \frac{32400\times 100}{225\times 100}$

$Mark\ up\ percentage = \frac{32400}{225}$

Markup percentage = 144 %

Therefore the markup percentage is 144% .
