There is 208 people in one movie theater.
There are 78 fewer people in the next. Subtract 208 and 78
208 - 78 = 130
There are 130 people in the next movie theater
-------------------------------------------------------------------------------------------------------------------
To find the total, add the two total numbers of each theater together.
130 + 208 = 338
-------------------------------------------------------------------------------------------------------------------
338 is the total amount of people.
hope this helps
