A store paid $12 for a sweatshirt and sold the sweatshirt of $19.20. What was the percent markup (increase) of the sweatshirt? *
Nookie1986 [14]

The percent markup of the sweatshirt is 60%

Here, we want to calculate the percenatge of profit made by the store

Mathematically;

\text{Percentage markup = }\frac{(sales\text{ price-cost price)}}{\cos t\text{ price}}\text{ }\times\text{ 100\%}

From the question, we can deduce the following;

cost price is the price the store bought the sweatshirt = $12

sales price is the amount in which they sold the sweatshirt = $19.20

Thus, we proceed to substitute these values into the markup equation above;

\begin{gathered} \text{Perecentage markup = }\frac{(19.20-12)}{12}\text{ }\times\text{ 100\%} \\  \\ \text{Percentage markup = }\frac{7.20}{12}\text{ }\times\text{ 100\%} \\  \\ =\text{ 60\%} \end{gathered}

IRISSAK [1]

Answer:

273 people.

Step-by-step explanation:

Given that,

Total number of people working on an office building = 1092

The building has 4 floors, and the same number of people work on each floor.

We need to find how many people work on each floor. Let there are n people in each floor.

n = Total number of people/Total number of floors

n=\dfrac{1092}{4}\\\\n=273

So, there are 273 people working on each floor.
