Answer 2

Calculation of the Cost of the Tool Set

To calculate the final cost of the tool set, we need to consider the initial price, the 5% decrease, and the subsequent 10% increase.

Let's assume the initial price of the tool set is 160 грн.

1. 5% Decrease: The tool set decreased in price by 5%. To calculate the new price after the decrease, we can multiply the initial price by (1 - 0.05). - New price after the 5% decrease: 160 грн * (1 - 0.05) = 152 грн.

2. 10% Increase: After the 5% decrease, the tool set increased in price by 10%. To calculate the final price after the increase, we can multiply the price after the 5% decrease by (1 + 0.10). - Final price after the 10% increase: 152 грн * (1 + 0.10) = 167.2 грн.

Therefore, the final cost of the tool set is approximately 167.2 грн.

Please note that the calculations above are based on the assumption that the initial price of the tool set is 160 грн.
