To determine what percent of Marcus's monthly income he spent on food, we need to know what his monthly income is. However, if we assume you have that information, here's how to calculate the percentage:
The formula for calculating the percentage is:
\[ \text{Percentage} = \left( \frac{\text{Amount spent}}{\text{Total income}} \right) \times 100 \]
Let’s denote Marcus's monthly income as \( I \).
So, if Marcus spent $480 on food, the calculation would be:
\[ \text{Percentage} = \left( \frac{480}{I} \right) \times 100 \]
If you provide Marcus's monthly income, we can plug it into this formula to calculate the exact percentage.
