Question

finding percent change
jose and a group of friends bought concert tickets for $257. the booking agency also charged a fee, bringing the total cost to $274.99. the amount of change is $17.99.
what is the percent increase in the cost due to the fee?
○ 6%
○ 7%
○ 8%
○ 9%

Explanation:

Step1: Recall percent increase formula

The formula for percent increase is $\text{Percent Increase} = \frac{\text{Amount of Change}}{\text{Original Amount}} \times 100\%$.

Step2: Identify values

Original amount (cost of tickets) = $\$257$, Amount of change (fee) = $\$17.99$.

Step3: Substitute into formula

$\text{Percent Increase} = \frac{17.99}{257} \times 100\%$. Calculate $\frac{17.99}{257} \approx 0.07$, then $0.07 \times 100\% = 7\%$.

Answer:

7%
