Elliot Glenn · Answer 1

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.
