Emily bought 9 packs of candy necklaces to give her classmates at school for Valentine’s Day. Each pack had 8 candy necklaces in it. Emily opened one pack at a time. After her classmates took as many as they wanted, there were 40 candy necklaces left. How many packs did Emily open for her classmates?
How many candy necklaces did Emily buy? ** Emily bought 9 packs of candy necklaces * 8 candy necklaces in a pack = <<9*8=72>>72 candy necklaces.
How many candy necklaces did Emily’s classmates take? ** Her classmates took 72 candy necklaces – 40 candy necklaces left = <<72-40=32>>32 candy necklaces
How many packs did Emily open for her classmates? ** Since each pack contained 8 necklaces, this means 32 / 8 = <<32/8=4>>4 packs of candy necklaces were opened.
