7 tickets: 7(t + 11) + 14
Distribute the 7 inside the parentheses.
(7t + 77) + 14
Add 77 and 14.
7t + 91
(7t + 77) + 14 and 7t + 91 are two expressions equivalent to the cost expression.
Now plug in 33 for t in the original cost expression.
7(t + 11) + 14
7(33 + 11) + 14
Distribute 7 inside the parentheses.
(231 + 77) + 14 = 322
