Please help me!! I really need it!! I Could fail the 7th grade
babymother [125]

Answer:

Step-by-step explanation:

Price of one ticket   = $4

Price of t tickets = 4t

1) 4t + 72 > 400

   t >  (400-72)/4

2) 4t + 72 > 400      

4t + 72 - 72 > 400 - 72    {subtract 72 from both sides}

4t > 328

4t/4 > 328/4      {divide both sides  by 4}

t >  82
