Answer 2

Calculation of the Decrease in Purchasing Power

To calculate the percentage by which Irina can now buy fewer groceries with her scholarship compared to before, we need to consider the increase in her scholarship and the increase in food prices.

Let's assume that Irina's scholarship for the previous year was 100 units. According to the information provided, her scholarship increased by 10%, resulting in a new scholarship amount of 110 units. Additionally, food prices increased by 25%.

To calculate the decrease in purchasing power, we can use the following formula:

Decrease in Purchasing Power = (Increase in Food Prices / Increase in Scholarship) * 100

Let's calculate the decrease in purchasing power:

Increase in Food Prices = 25%

Increase in Scholarship = 10%

Decrease in Purchasing Power = (25 / 10) * 100 = 250%

Therefore, Irina can now buy 250% less groceries with her scholarship compared to before.

Please note that this calculation assumes that the increase in food prices affects the entire budget for groceries and that the scholarship increase is the only source of income for Irina. In reality, individual spending habits and other sources of income may also impact the purchasing power.
