Answer:
25
Step-by-step explanation:
Ticket sale (student) = $8
Ticket sale (adult) = $13
The hall can contain 70 people.
Number of adult tickets sold = 41
Cost of show = $730
Let the number of student ticket sold = x
Setting an algebraic equation to show represent the cost of the show and set minimum target of ticket to be sold.
730 = (41 * 13) + (x * 8)
730 = 533 + 8x
8x = 730 - 533
8x = 197
X = 197 / 8
x = 24.6 = 25
The minimum number of student tickets to be sold is 25

Answer:-24
Step-by-step explanation:
-72+48=-24
-5=-5
-12+7 = x+3
-5 = x+3
-5-3 =x
x = -8
-12+7 = -8 +3
-5 = -5
