Question

1. bruce spent $30 on lunch. if he had $55 in his wallet, what percent of his money did he spend on lunch?

Explanation:

Step1: Use the percentage formula

The formula for percentage is $\frac{\text{part}}{\text{whole}}\times100\%$. Here, the part is the money spent on lunch ($30$) and the whole is the total money in the wallet ($55$). So the expression is $\frac{30}{55}\times100\%$.

Step2: Calculate the value

First, $\frac{30}{55}=\frac{6}{11}\approx0.545455$. Then, $0.545455\times100\% = 54.5455\%\approx54.55\%$ (rounded to two decimal places).

Answer:

$54.55\%$
