Answer:
16 packs of spearmint gum
Step-by-step explanation:
Let x = no. of packs of spearmint gum
2x = no. of packs of green apple gum
2x - 6 = no. of packs of cinnamon gum
x + 2x + 2x - 6 = 74
5x - 6 = 74
5x = 80
x = 16 packs of spearmint gum
2x = 2(16) = 32 packs of green apple gum
2x - 6 = 32 - 6 = 26 packs of cinnamon gum
