Answer:
The total number of people went to the movie is 7 .
Step-by-step explanation:
Given as :
The cost of each people went to movie = $ 6.50
The price spent on snacks = $ 17.50
The total amount spent = $ 63
Let The total number of people went to movie = Isaballa + x friend's
I.e The total number of people went to movie = 1 + x
Now, According to question
( 1 + x ) × $ 6.50 + $ 17.50 = $ 63
Or, ( 1 + x ) × $ 6.50 = $ 63 - $ 17.50
Or, ( 1 + x ) × $ 6.50 = $ 45.5
∴ 1 + x = [tex]\frac{45.5}{6.5}[/tex]
I.e 1 + x = 7
Or, x = 7 - 1 = 6
So, The number of friend's went to movie along with Isaballa is 6
Hence The total number of people went to the movie is 7 . Answer
