What math concepts will students use to determine the savings for Maria to carpet her room?

To determine the savings for Maria to carpet her room, students will need to apply several mathematical concepts that are relevant to the problem. Multiplication plays a crucial role in calculating the total cost of carpeting, as they will need to multiply the price per square foot by the total area of the room. Geometry comes into play when students determine the area of the room, as they must calculate the length and width to find the total square footage that needs to be carpeted, which is a fundamental aspect of understanding and applying geometric principles.

Additionally, students may need to utilize subtraction to find the difference between the original price of carpeting and any discounts or savings they receive. This step will require a straightforward subtraction process to identify how much Maria will actually pay after applying any savings. Lastly, conversion might be necessary if measurements are given in different units (for instance, converting feet to inches), ensuring that all calculations are accurate and consistent.

Thus, the option that includes multiplication, geometry, subtraction, and conversion accurately reflects the range of mathematical concepts that students will engage with to effectively determine Maria's savings on carpeting her room.
