-2) You and your friend went to the movies. Tickets cost $5.50 each and a popcorn with 2 sodas cost
$6.50. What is the total after 5% sales tax is added?

$18.38

Step-by-step explanation:

The tickets cost $5.50 each. 2 people are going, which means that you are going to buy two tickets, one for each person:

5.50 x 2 = 11

The popcorn and sodas cost $6.50, so you are going to add that to the cost of the tickets:

11 + 6.50 = 17.50

Divide the number you have by a 100:

17.50 ÷ 100 = 0.175

Multiply what you have by 5:

0.175 x 5 = 0.875

Round that off to two decimal places:

0.875 = 0.88

Add to the cost of the tickets, popcorn and sodas:

0.88 + 17.50 = 18.38

$18.38

Step-by-step explanation:

Let's build an expression to help answer this problem.

2 tickets + popcorn and sodas + tax =

2(5.50) + 6.50 + T(0.05) where T is equal to the total prior to tax.

Now let's solve for T:

11 + 6.50 = T = 17.50

Now let's find the tax:

17.50(0.05) = 0.875

Total after tax = 17.50 + 0.875 = 18.38 rounding to the nearest cent.

Hope this helped!
