Final answer:
Mei Jung paid 25% of the total dinner cost by dividing the amount she paid, $15, by the total cost, $60, and then multiplying by 100.
Step-by-step explanation:
The subject of this question is Mathematics, specifically dealing with the concept of percentages in a real-life context. To calculate what percent Mei Jung paid for her portion of the dinner, we use the formula: (Part / Total) × 100. So, Mei Jung's portion percentage is calculated as follows:
- Determine the total cost of the dinner, which is given as $60.
- Identify the amount Mei Jung paid, which is $15.
- Divide the amount Mei Jung paid by the total cost of the dinner: $15 / $60.
- Multiply this result by 100 to find the percentage: ($15 / $60) × 100 = 25%.
Hence, Mei Jung paid 25% of the total dinner cost.
