Question

If the Revenue for the week is $2000, and labor cost consists of two workers earning $8 per hour who work 40 hours each, what is labor cost as a percentage of Revenue?

Answer 1

8×40×2=640
labor cost as a percentage of Revenue
(640/2000)×100=32%

Answer 2

2 workers, each 8 per hour, for 40hrs a week, so one earns 8 * 40, or 320 bucks, is two workers, so 320 + 320 or 640 bucks

if 2000 is the 100%, how much is 640 in percentage off of it?

well
`\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 2000&100\\ 640&x \end{array}\implies \cfrac{2000}{640}=\cfrac{100}{x}`

solve for "x"
