we will start with the first statement
It costs $12 to go to the movies
$6 is the cost of a popcorn
when you see a movie, you will be paying a fixed amount for the tickeck which is $12
In the process of seeing the movie, you will want to consume more than one popcorn depending on the money you have on you
let the number of popcorn consumed be p
since, the amount per popcorn is $6
therefore, the cost of popcorn consumed will be
$6 * p
= 6p
The total cost to see the movie and also buy popcorn is
= cost to go to the movie + the cost of popcorn consumed
= 12 + 6p
the answer for part A statement is 12 + 6p
The second part of the statement
How much will it cost to to go to the movies and buy 5 popcorns
from the above algebraic expression
total cost = 12 + 6p
p = no of popcorn
p = 5
total cost = 12 + 6(5)
total cost = 12 + 30
total cost = $42
The answer is $42
