120 children's hats at $4 each would have cost $480. The actual total sales was $720, which is $240 more than that.

Each adult's hat costs $3 more than each children's hat. The number of adult's hats needed to be sold to make up that other $240 is 240/3 = 80.

ANSWER: She sold 80 adult's hats and 120-80 = 40 children's hats.
