Question

The local movie theater collected a total of 8250 last night, of which 45% came from sales at the concession stand. How much money did the theater collect at the concession stand

Answer 1

The theater collected $3,712.50 at the concession stand. How I determined this answer:

Alright, so you already know the total amount the theater collected ($8,250) and the percent of sales which came from the concession stand (45%). Your first step is to change the given percentage into a decimal, as shown below:

To change 45% into a decimal, you have to move the invisible decimal point two places to the left:
45(.)% becomes .45

Now that you have changed your percent into a decimal, your next step is to multiply the total sales the theater made last night with your decimal, as shown below:

Multiply the total sales ($8,250) x (.45)
$8,250 x .45 = $3,712.50.

So the theater made a total of $3,712.50 at the concession stand last night.
