10. a store manager instructs his employees to mark up all items by 30%. a store clerk puts a price - tag of $30 on an item that the store bought for $27. as an employee, you notice that this selling price is incorrect. a. find the correct selling price. round to the nearest dollar. b. what was the clerks likely error?

Answer

Explanation:

Step1: Calculate markup amount

The cost - price of the item is $C = 27$. The markup percentage is $r=30%=0.3$. The markup amount $M$ is calculated by $M = C\times r$. So, $M=27\times0.3 = 8.1$.

Step2: Calculate selling price

The selling price $S$ is the sum of the cost - price and the markup amount, i.e., $S=C + M$. Substituting the values of $C$ and $M$, we get $S=27 + 8.1=35.1\approx35$.

Step3: Analyze clerk's error

The clerk likely just added a flat amount of $3$ instead of calculating 30% of 27 and adding it to 27.

Answer:

a. $35$ b. The clerk likely added a flat amount of $3$ instead of calculating 30% of the cost - price and adding it to the cost - price.
