Answer :

hello

to solve this question, we should write out an expression

the cost of an item = x

there's 45% discount on x

let y represent the discount price

[tex]\begin{gathered} \frac{45}{100}=\frac{y}{x} \\ 0.45=\frac{y}{x} \\ y=0.45x \end{gathered}[/tex]

the new price to pay after the discount =

[tex]x-(0.45x)=\text{new price}[/tex]

the new price of the item = x - (0.45x)
