WILL GIVE BRAINLIEST. Tickets to a show cost $3 for students and $7 for adults. If 250 tickets were sold and ticket sales totale
Diano4ka-milaya [45]

Answer:

88 adult tickets were sold

Step-by-step explanation:

3s + 7a = 1102

(s + a = 250)-3

   3s + 7a = 1102

+ -3s - 3a = -750      Add these equations together

4a = 352                  Divide both sides by 4

a = 88

Now plug this into the second equation

s + a = 250

s + 88 = 250

  - 88     - 88        Subtract 88 from both sides

s = 162

If this answer is correct, please make me Brainliest!
