Answer: 22
Step-by-step explanation:
Given : Before a show, there are 8 people in a theater. Five groups of 4 people enter, and then three groups of 2 people leave.
The expression to find how many people are in the theater is given as :
[tex]8+5(4)-3(2)[/tex]
Using BODMAS (Bracket , Of , Divide , Multiplication, Add, Subtract), we first open brackets .
[tex]8+5\times4-3\times2\\\\=8+20-6[/tex]
Now again using BODMAS , first we solve addition operation, then subtraction.
[tex]=28-6=22[/tex]
Hence, the number of people are in the theater= 22
