Answer :
To calculate the percent change in the price of the coffee, we can use the following formula:
- Percent change = (new value - old value) / old value * 100
In this case, the old value is 2 dollars, and the new value is 2 + 1 = 3 dollars. Plugging these values into the formula, we get:
- Percent change = (3 - 2) / 2 * 100
Simplifying this expression, we get:
- Percent change = 1 / 2 * 100
This simplifies to:
- Percent change = 0.5 * 100
Which is equal to:
- Percent change = 50
Therefore, the percent change in the price of the coffee is 50%. This means that the price increased by 50% when it was increased by 1 dollar.
