Question

recycling 100 aluminum cans can save enough energy to light up a room for 2 weeks. estela wants to find the savings for recycling even more cans so she can use the information to promote a school recycling program. enter the number of weeks of energy saved by recycling 200 cans.

cans recycled	100	200

Explanation:

Step1: Analyze the relationship

We know that recycling 100 cans saves 2 weeks of energy. We need to find the energy saved for 200 cans. Since 200 is 2 times 100 (because $200\div100 = 2$), the energy saved should also be 2 times the energy saved for 100 cans.

Step2: Calculate the energy saved

The energy saved for 100 cans is 2 weeks. So for 200 cans, we multiply the energy saved for 100 cans by 2: $2\times2 = 4$.
