an electronic company produces a mobile device for $558 the device is sold for $1499 complete the proportion to determine the percent of change

change/100=blank/blank

558 - 1499 1499 - 558 558 1499

what is the percent of change in this situation blank round the answer to the nearest whole percent

To determine the percent of change from the production cost of the mobile device to its selling price, we can use the formula for percent change:

\[ \text{Percent Change} = \frac{\text{Change}}{\text{Original Value}} \times 100 \]

  1. Determine the change: \[ \text{Change} = \text{Selling Price} - \text{Cost Price} = 1499 - 558 = 941 \]

  2. Using the original value (the cost price, which is 558): \[ \text{Percent Change} = \frac{941}{558} \times 100 \]

  3. Calculate the percent change: \[ \text{Percent Change} \approx \frac{941}{558} \approx 1.6844 \] \[ 1.6844 \times 100 \approx 168.44% \]

  4. Round to the nearest whole percent: \[ \text{Percent Change} \approx 168% \]

Thus, the percent of change in this situation is approximately 168%.

To fill in your proportion format: \[ \frac{941}{558} = \frac{\text{Percent Change}}{100} \] Where "blank" can be filled as \( 941 \) and \( 558 \).

Got it! Let's set it up in the format you've shown:

To determine the percent of change in the format you provided, we need to represent the percent change as a fraction in proportion format:

Given:

  • Change = Selling Price - Cost Price = \(1499 - 558 = 941\)
  • Percent change = \( \text{Percent Change} \)

Using your proportion setup, we can represent it as:

\[ \frac{941}{100} = \frac{\text{Percent Change}}{100} \]

In this case, you can fill in the blanks as follows:

\[ \frac{941}{100} = \frac{\text{Percent Change}}{1499 - 558} \]

Or simply,

\[ \frac{941}{100} = \frac{\text{Percent Change}}{558} \]

So to fill in the blanks as per your format:

\[ \text{Change} / 100 = 941 / 558 \]

Thus, your completed proportion is:

\[ \frac{941}{100} = \frac{\text{Percent Change}}{558} \]

And to clarify further, the percent change we previously calculated was approximately \(168%\). So you can write:

\[ \frac{941}{100} = \frac{168}{558} \]

I hope this aligns with what you were looking for!
