9. dtlr is offering a 20% discount on all items. if a shirt originally costs $75, how much will it cost with…

Explanation:

Step1: Calculate the discount amount

The discount is 20% of the original price. The formula for finding a percentage $p$ of a number $x$ is $p\times x$. Here, $p = 0.2$ (since 20%=$\frac{20}{100}=0.2$) and $x = 75$. So the discount amount $d=0.2\times75 = 15$.

Step2: Calculate the final price

The final price $f$ is the original price minus the discount amount. So $f=75 - 15=60$.

Answer:

$60$
