Marcy has 567 earmuffs in stock if she can put 18 earmuffs on each shelf how many shelves does she need for all of the earmuffs I also need to estimate the whole problem

Respuesta :

Estimate 34.
567 divide 18 =31.5
therefore she needs 32 shelves to stock all the earmuffs. 
She's going to need about 30.
