Question

1.Noah has a coupon for 30% off at his favorite clothing store. He uses it to buy a hoodie and a part of jeans.If the regular price of an item is x dollars and the item is 30% off, how wouldyou find the new price?

Answer 1

If the item price is x dollars with 30% off, this item cost

`\begin{gathered} x-(0.3\cdot x)=x(1-0.3)=x\cdot0.7 \\ \end{gathered}`

where 0.3 correspond to 30%.

For instance, lets suppose that the item cost $50, then we have

`50\cdot0.7=35`

that is, the item will cost $35.
