Answer

Explanation:

Step1: Calculate Zeke's total allowance

Zeke gets $5 per week for 13 weeks. So the total allowance is $5\times13 = 65$.

Step2: Calculate the amount Zeke spent

The total allowance is 65 and he had 13 left. So the amount spent is $65 - 13=52$.

Step3: Calculate the percentage spent

The percentage spent is $\frac{52}{65}\times100%$. Since $\frac{52}{65}=0.8$, then $0.8\times 100% = 80%$.

Answer:

B. 80%
