H = 0.75n is the expression as a product to represent the sale price of the shirt
<em><u>Solution:</u></em>
Given that, Miranda buys a shirt at the mall
She has a coupon for 25 % off
To find: Expression as a product to represent the sale price of the shirt
Let "H" be the sale price of shirt
Let "n" be the original price of shirt
From given statement,
discount = 25 % of original price
Therefore,
discount = 25 % of n
<em><u>The sale price is given as:</u></em>
<h3>Sale price = Original price - discount price</h3>
H = n - 0.25n
<h3>H = 0.75n</h3>
Thus expression as a product to represent the sale price of the shirt is found
