You have to watch 30 movies to earn a free movie pass.

Step-by-step explanation:

Given,

Points earned for each movie = 2 points

Current points = 40 points

Free movie pass = 100 points

Let,

x be the number of movies you have to watch.

2*number of movies + current points = 100

$2x+40=100$

Subtracting 40 from both sides

$2x+40-40=100-40\\2x=60$

Dividing both sides by 2

$\frac{2x}{2}=\frac{60}{2}\\x=30$

You have to watch 30 movies to earn a free movie pass.

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.
