Question

Katie has $32 to spend on party supplies after buying 9 packs of noisemaker she has $20 left how much did each pack of noise maker cost

Answer 1

total money she has is 32 $

now after buying she has left only with 20$

so she spent 32 - 20 = 12 $

she spent 12 $ for buying 9 packs of noisemaker,

9 Pack cost = 12 $

1 pack cost = 12 / 9

= 4/3 = 1.3333 $

so cost of each pack of noise is 1.33 $
