Answer 3

Calculation of the Cost of Construction Materials

To calculate the cost of construction materials, we need to determine the percentage of the total amount spent on labor and the remaining percentage spent on materials.

Given that 35% of the total amount was spent on labor, we can calculate the remaining percentage spent on materials by subtracting 35% from 100%:

100% - 35% = 65%

Therefore, 65% of the total amount was spent on construction materials.

To find the cost of the construction materials, we need to calculate 65% of the total amount spent on the school's repair.

According to the information provided, the total amount spent on the repair of the school was 4340 UAH.

Let's calculate the cost of the construction materials:

65% of 4340 UAH = 4340 UAH * 0.65 = 2811 UAH

Therefore, the cost of the construction materials was 2811 UAH.
