Distribute +1
78=1/2x+x-6
combine like terms
1=(2/2)
(1/2)+(2/2)= 3/2
78=3/2x-6
Add 6 to both sides
84=3/2x
Divide by (3/2)
x=$56=adult ticket
Child ticket = x-6=56-6=$50
$50
Find the factors
The factor is -2
Finally equation:
(x-2)(x-2)
Well, since half is when you divide something by 2, divide 30 by 2
Then, you get 15
So Kristen made 15 sundaes!
Hope this helped!
