Read the scenario and calculate the final remaining amount. Enter only the numerical value in the blank.

Cevap:A naval shipyard crew is assigned to apply a specialized anti-corrosion coating to

3,200

square feet of a submarine's hull. During the first week of the project, the crew successfully coats

45\%

of the total area. In the second week, due to bad weather, they only manage to coat

25\%

of the remaining uncoated area. Based on this progress, exactly 【1320】 square feet of the hull still need to be coated.

1320

The correct calculation requires adjusting the base for the second percentage. First, find

45\%

of the original

3,200

square feet, which is

1,440

square feet. This leaves

1,760

square feet uncoated. The second week's progress is

25\%

of that remaining

1,760

square feet, equaling

440

square feet. Subtracting this from the

1,760

gives a final uncoated area of

1,320

square feet.

Calculate the area coated during the first week.

3,200 \times 0.45 = 1,440

square feet.

To find the initial amount completed, multiply the total area by the first week's completion percentage.

Calculate the remaining uncoated area after the first week.

3,200 - 1,440 = 1,760

square feet.

Subtract the coated area from the total area to establish the new base amount for the second week's calculation.

Calculate the area coated during the second week.

1,760 \times 0.25 = 440

square feet.

Multiply the remaining uncoated area by the second week's completion percentage.

Calculate the final remaining uncoated area.

1,760 - 440 = 1,320

square feet.

Subtract the second week's coated area from the previously remaining area to find the final answer.

Calculating successive percentages by identifying the correct base quantity for each step.
