I need help solving this problem.

  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.

entering that problem on the tube might get you an answer

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
