A restaurant updated the prices of items on their menu. The old price of a veggie sandwich was $6.50. The new price is $8.39. What is the percent increase in the price of the sandwich? Round to the nearest whole percent

Answer 1

To calculate the percent increase in the price of the veggie sandwich, you can follow these steps:

1. Find the difference in price: $$\text{Difference}=\text{New Price}-\text{Old Price}=8.39-6.50=1.89$$

2. Calculate the percent increase: $$\text{Percent Increase}=\left(\frac{\text{Difference}}{\text{Old Price}}\right)\times 100=\left(\frac{1.89}{6.50}\right)\times 100$$

3. Perform the calculation: $$\frac{1.89}{6.50}\approx 0.2900$$ $$\text{Percent Increase}\approx 0.2900\times 100\approx 29.00$$

4. Round to the nearest whole percent: $$\text{Percent Increase}\approx 29$$

Therefore, the percent increase in the price of the veggie sandwich is 29%.
