Answer:
30
Step-by-step explanation:
Let d represent the number of dozens of golf balls ordered. Then 12d is the number of balls.
The cost of the Light Hit balls will be (2.00)(12d). The cost of the Pro Sport balls will be (0.90)(12d). The difference in cost is ...
(2.00)(12d) -(0.90)(12d) = 396.00
1.10d = 33 . . . . . divide by 12, combine terms
d = 30 . . . . . . . divide by 1.10
30 dozen balls of each brand were ordered.
