Question

enter the number of weeks of energy saved by recycling 300 cans.
cans recycled | 100 | 200 | 300
energy saved (weeks) | 2 | 4 |

Explanation:

Step1: Identify the pattern

We see that when cans recycled increase from 100 to 200 (double), energy saved increases from 2 to 4 (double). So it's a proportional relationship.

Step2: Calculate for 300 cans

Since 300 is 3 times 100, energy saved should be 3 times 2. So \( 3\times2 = 6 \).

Answer:

6
