To determine what percentage of the serving price is represented by the cost of the raw ingredients, you can use the following formula:
\[ \text{Percentage of raw ingredients} = \left( \frac{\text{Cost of ingredients}}{\text{Serving price}} \right) \times 100 \]
Plugging in the values provided:
- Cost of ingredients = \(0.83\) dollars
- Serving price = \(5.75\) dollars
Now calculate:
\[ \text{Percentage of raw ingredients} = \left( \frac{0.83}{5.75} \right) \times 100 \]
Calculating this step by step:
- \( \frac{0.83}{5.75} \approx 0.1443\)
- \(0.1443 \times 100 \approx 14.43\)
Rounding \(14.43\) to the nearest tenth of a percent gives you \(14.4\).
Thus, to the nearest tenth of a percent, raw ingredients make up 14.4% of the serving price.
