Question

One week gas was $2.50 per gallon. The next week gas increased to $3.50 per gallion. By how much is the percent increase

Answer 1

To find the percent increase in the price of gas from $2.50 to $3.50 per gallon, calculate the difference, divide it by the original price, and multiply by 100, resulting in a 40% increase.

Step-by-step explanation:

The student is asking how to calculate the percent increase in the price of gas from $2.50 per gallon to $3.50 per gallon. To find the percent increase, you subtract the original price from the new price. Then you divide the increase by the original price, and finally, multiply the result by 100 to get the percentage.

Here is the step-by-step calculation:

1. Calculate the increase: $3.50 - $2.50 = $1.00
2. Divide the increase by the original price: $1.00 / $2.50 = 0.4
3. Multiply by 100 to get the percentage: 0.4 × 100 = 40%

Therefore, the price of gas increased by 40% from $2.50 per gallon to $3.50 per gallon.
