Answer 1

Can Oxana receive change only in coins of 5 kopecks, 10 kopecks, 25 kopecks, or 50 kopecks?

To determine if Oxana can receive change only in coins of 5 kopecks, 10 kopecks, 25 kopecks, or 50 kopecks, we need to find the possible combinations of coins that add up to 2.25 hryvnias (2.25 UAH).

Let's analyze each option:

1) Change in 5 kopecks coins: If Oxana receives change only in 5 kopecks coins, the total number of coins she can receive would be 45 (2.25 UAH / 0.05 UAH).

2) Change in 10 kopecks coins: If Oxana receives change only in 10 kopecks coins, the total number of coins she can receive would be 22 (2.25 UAH / 0.10 UAH).

3) Change in 25 kopecks coins: If Oxana receives change only in 25 kopecks coins, the total number of coins she can receive would be 9 (2.25 UAH / 0.25 UAH).

4) Change in 50 kopecks coins: If Oxana receives change only in 50 kopecks coins, the total number of coins she can receive would be 4 (2.25 UAH / 0.50 UAH).

Based on the calculations above, Oxana can receive change in any of the mentioned coin denominations. The number of coins she would receive depends on the specific denomination chosen.

Please note that the calculations are based on the assumption that Oxana receives the exact amount of change without any rounding or additional coins.
