Brian is ordering tickets online for a concert. the price of each ticket for the concert is t dollars. for online orders there is an additional charge of $11 per ticket and a service charge of $14 for the entire order. the cost for 7 tickets can be represented by the expression 7(t + 11) + 14. write two expressions equivalent to the cost expression. then, find the total cost of brian’s online order if the price of each ticket for this concert is $33

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.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
