Tyrone's office recycled a total of 308 kilograms of paper over 28 weeks. After 33 weeks, how many kilograms of paper will Tyrone's office have recycled? Assume the relationship is directly proportional.

Respuesta :

We can use a proportion to solve

308 kilograms x kilograms

---------------------- = ----------------------

28 weeks 33 weeks

Using cross products

308 * 33 = 28 * x

10164 = 28x

Divide each side by 28

10164/28 = 28x/28

363 = x

They will recycle 363 kilograms
