Answer

Explanation:

Step1: Recall percentage - tip formula

The formula to find the percentage of a tip is $\text{Percentage}=\frac{\text{Tip Amount}}{\text{Bill Amount}}\times100%$.

Step2: Calculate for a $13 tip

Given the bill amount is $50. Substitute into the formula: $\text{Percentage}=\frac{13}{50}\times100%$. First, $\frac{13}{50}=0.26$, then $0.26\times100% = 26%$.

Step3: Calculate for a $12.50 tip

Substitute the tip amount of $12.50 and bill amount of $50 into the formula: $\text{Percentage}=\frac{12.50}{50}\times100%$. First, $\frac{12.50}{50}=0.25$, then $0.25\times100% = 25%$.

Answer:

The percentage of a $13 tip is 26%. The percentage of a $12.50 tip is 25%.
