Write the equation.
45 * 0.8 = p
ok thanks
You're welcome.
To find the price of the new jacket, we need to subtract the discount from the original price of $45. The discount is calculated as a percentage of the original price, which in this case is 20%. Let's write the equation:
New Price = Original Price - (Discount Percentage × Original Price)
In this case, the original price is $45, and the discount percentage is 20%. Let's substitute these values into the equation:
New Price = $45 - (20% × $45)
Now, we need to convert the discount percentage to its decimal form. To do this, divide the percentage by 100:
New Price = $45 - (0.20 × $45)
Now we can calculate the new price:
New Price = $45 - $9
New Price = $36
Therefore, the price of the new jacket after a 20% discount is $36.
