Step-by-step explanation:
Violet bought 120 at "3 for $2".
how many groups of 3 did she buy ?
120/3 = 40 groups of 3.
so, she paid 40×2 = $80.
Harry bought 120 at "6 for $5".
how many groups of 6 did he buy ?
120/6 = 20 groups of 6.
so, he paid 20×5 = $100.
that means Violet paid 100 - 80 = $20 less than Harry.
