Using unitary method, we find that Theater Mania offer the best buy of popcorn.
The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
We calculate the price of popcorn of size 1 at each given theater.
Cine Plex theater:
Price of size 100 popcorn = $8.25
Price of size 1 popcorn = [tex]\frac{8.25}{100} = 0.0825[/tex]
Mr. Movie theater:
Price of size 96 popcorn = $7.00
Price of size 1 popcorn = [tex]\frac{7}{96} = 0.073[/tex]
Stadium Cinema:
Price of size 112 popcorn = $6.50
Price of size 1 popcorn = [tex]\frac{6.50}{112} = 0.058[/tex]
Theater Mania:
Price of size 136 popcorn = $7.50
Price of size 1 popcorn = [tex]\frac{7.50}{136}[/tex] [tex]= 0.055[/tex]
