The table shows the number of tickets each team sold. If they sold the same, how many did each sell? Remember to continue beyond
BartSMP [9]

Answer:

  each sold 60 tickets

Step-by-step explanation:

Apparently, you're supposed to set the expressions equal and solve for t; then find the values of the expressions.

  60(t -1) = 20(t +1)

  60t -60 = 20t +20  . . . . . eliminate parentheses

  40t = 80 . . . . . . . . . . . . . . add 60 -20t

  t = 2 . . . . . . . . . . . . . . . . . . divide by 40

__

  60(2 - 1) = 60 . . . . . solve for Falcons sales

  20(2 + 1) = 60 . . . . .solve for Eagles sales (should be equal; it is)

Each team sold 60 tickets.
