Respuesta :

(8 wands) x = $ 50
so

x = (50 / 8) = (25 / 4) = $ 6.25 per wand

Checking Prices
a) 4 x = 20
       x = $ 5, Does not have the same price per wand as glitter wands

b) 6 x = 37.50
       x = (37.50 / 6) = $ 6.25,  Has the same price per wand as glitter wands

c) 10 x = 65
         x = 6.5, Does not have the same price per wand as glitter wands
