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


The total cost of Brain's online order is $322.
