Final answer:
To find the percentage of the cost that Amakiri spent on the camera, we can use the given information to calculate the cost of the camera and film. By solving the equation, we find that the cost of the film is N12.5. Then, we divide the cost of the camera by the total cost of both items and multiply by 100 to find the percentage.
Step-by-step explanation:
To find the percent of the cost that Amakiri spent on the camera, we need to determine the cost of the camera and the film. Let's assume the cost of the film is x. According to the given information, the camera cost N100 more than the film, so the camera cost would be x + N100. The total cost of the camera and film is given as N125, so we can write the equation as: x + (x + N100) = N125.
Simplifying the equation gives us: 2x + N100 = N125. Subtracting N100 from both sides gives us: 2x = N25. Dividing both sides by 2 gives us: x = N12.5. Therefore, the cost of the film is N12.5.
Now, we can calculate the percentage of the cost that Amakiri spent on the camera. The camera cost N100 more than the film, which is N12.5. So, the camera cost would be N12.5 + N100 = N112.5. To find the percentage, we divide the cost of the camera (N112.5) by the total cost of both items (N125) and multiply by 100:
Percentage = (N112.5 / N125) x 100 = 90%.
