Question

Amy wants to buy a pair of jeans that cost $65. Today the store is offering a straight discount of 25%. Calculate her savings and cost after the discount.

Answer 1

her savings is the 25% amount... well, if we take 65 to be the 100%, how much is 25% of that?


`\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 65&100\\ x&25 \end{array}\implies \cfrac{65}{x}=\cfrac{100}{25}`

solve for "x", that's her savings

the cost of the jeans is 65 - x

Answer 2

Amy's discount is $16.25, and the cost after the discount is $48.75.
