Question

The oringinal cost of a lamp is $18.95. the lamp is on sale for 25% off. how much will you pay?

Answer 1

100% - 25% = 75%

so, if 18.95 is the 100%, how much is the 75% of that?


`\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 18.95&100\\ x&75 \end{array}\implies \cfrac{18.95}{x}=\cfrac{100}{75}`

solve for "x".
