Question

Justin and his friend Dan went to the movie. If they each bought popcorn for $4.25 and a soda for $2.25 what was their total bill after adding 5% tax?

Answer 1

To calculate Justin and Dan's total movie bill, add the cost of popcorn and soda for each, and then include the 5% tax. The subtotal is $13.00, and with the tax, the total comes to $13.65.

Step-by-step explanation:

The subject of this question is mathematics, specifically focusing on a real-life application related to calculating total bills, including taxes and tips. Justin and Dan's situation is a straightforward matter of first calculating the total cost of their purchases, and then adding on the appropriate tax percentage.

To find Justin and Dan's total bill at the movie theater, let's add together the cost of their popcorn and soda and then calculate the 5% tax. First, we combine the cost of popcorn ($4.25) and soda ($2.25) for each person, which amounts to $6.50 per person. As there are two people, we multiply this by two, resulting in a subtotal of $13.00.

Next, we calculate the 5% tax:
0.05 × $13.00 = $0.65

Finally, we add the tax to the subtotal to find the total bill:
$13.00 + $0.65 = $13.65
Therefore, Justin and Dan's total bill after adding 5% tax for the popcorn and soda at the movie theater is $13.65.

Answer 2

2(4.25 + 2.25) = 2(6.50) = 13...this is the cost without the tax

13 + 0.05(13) = 13 + 0.65 = 13.65 <=== total with the sales tax added
