Final answer:
The percent decrease for the price of a gallon of gas between the two weeks is approximately 7.11%.
Step-by-step explanation:
To find the percent decrease, we can use the formula:
Percent decrease = ((Original value - New value) / Original value) x 100
In this case, the original value is $3.23 and the new value is $3. We substitute these values into the formula and calculate:
Percent decrease = ((3.23 - 3) / 3.23) x 100 = (0.23 / 3.23) x 100 ≈ 7.11%
Therefore, the percent decrease for the price of a gallon of gas between the two weeks is approximately 7.11%.
