So.. hmmm if we take "x" to be the 100% sale price before tax, $76 is really 9.5% of that

thus \bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
76&9.5\\
x&100
\end{array}\implies \cfrac{76}{x}=\cfrac{9.5}{100}

solve for "x"

A skier is trying to decide whether or not to buy a season ski pass. a daily pass is $75. A season ski pass is $350. The skier w
pishuonlain [190]
Since the skier has to rent skis for 30 dollars per day with both passes, we can ignore it while solving the question.

A season pass is 350, while a daily pass is 75.

\frac{350}{75} = \frac{25\times 14}{25\times 3} = \frac{14}{3} = 4 \frac{2}{3}

So a seasonal pass is equivalent to having 4.6667 daily passes. And you can't buy 0.6667 of a pass.

So, if you went at least 5 days with a seasonal pass, then the seasonal pass would be less expensive than a daily pass.

Given that W is directly proportional to the square of V, and W = 320 when V = 8, find W when V = 9.
lorasvet [3.4K]

The value of W when V = 9 is 405

<h3>How to solve for W?</h3>

The variation is a direct variation from W to V^2.

This means that:

W = kV^2

Where k is the constant of variation.

W = 320 when V = 8 means that:

320 = k * 8^2

Evaluate

320 = 64k

Divide both sides by 64

k = 5

Substitute k = 5 in W = kV^2

W = 5V^2

When V = 9, we have:

W = 5 * 9^2

Evaluate

W = 405

Hence, the value of W when V = 9 is 405
