Question

Illinois State tax is 4.98%. How much did Brody pay for a post card that cost $1.19?

Answer 1

so if we take 1.19 to be the 100%, what is 4.98% of that then?


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 1.19&100\\ a&4.98 \end{array}\implies \cfrac{1.19}{a}=\cfrac{100}{4.98}\implies \cfrac{1.19\cdot 4.98}{100}=a`

that much. close to 6 pennies.
