Question

Aniel's office had already recycled 18 kilograms this year before starting the new recycling plan, and the new plan will have the office recycling 2 kilograms of paper each week. How many weeks will it take Ariel's office to recyde a total of 24 kilograms of paper?

Answer 1

Already recycled = 18 kilograms

Recycled kilograms per week = 2

Number of weeks = x

Total kilograms of paper recycled (y) = 18+2x

y= 18+2x

If the total kilograms of paper recycled is 24:

24=18 +2x

Solve for x:

24-18 = 2x

6 = 2x

6/2 = x

3 = x

3 weeks
