Question

Today, everything at a store is on sale. The store offers a 45% discount. If the regular price of an item is x dollars, what is the price you pay after the discount? Write an algebraic expression.

Answer 1

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

`\begin{gathered} (45)/(100)=(y)/(x) \\ 0.45=(y)/(x) \\ y=0.45x \end{gathered}`

the new price to pay after the discount =

`x-(0.45x)=\text{new price}`

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