Answer:
Luis paid 3/5 of the original price
Step-by-step explanation:
Luis purchased a laptop with a fractional discount of 2/5 of the original price.
When dealing with fractional parts of a whole, the sum of all parts must equal 1. With this in mind, we can say:
Paid price + Discount price = Original price
Or, equivalently:
paid fraction + discount fraction = 1
From the above relation, it follows that:
paid fraction = 1 - discount fraction
[tex]\displaystyle \text{paid fraction }=1-\frac{2}{5}[/tex]
[tex]\displaystyle \text{paid fraction }=\frac{5-2}{5}[/tex]
[tex]\displaystyle \text{paid fraction }=\frac{3}{5}[/tex]
Luis paid 3/5 of the original price
