Answer:
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Step-by-step explanation:
We will write the equation to represent this scenario.
Let x be the number of people who went for movies.
Then the price of ticket for x people will be: 6.25x
They spent $12 on refreshments and a total of $30.75 so the equation will be:

solving the equation will give us total number of people
So,

Hence,

Answer:
22 pounds
Step-by-step explanation:
c+s=52, c = 52-s
3c+5s=200 
3(52-s) +5s = 200
156 - 3s +5s = 200
5s-3s = 200-156
2s = 44
Shrimp = 44/2 = 22 pounds
 
        
             
        
        
        
Hey there :)
Let 
p represent the number of bags to be bought
We need to collect 
30 stickers and each 
bag has 
3 stickers
                    3p                                =                        30
                      ↑                                                           ↑
Number of stickers in a bad       Number of stickers to be collected

 = 
 p = 10
p = 10We need to buy 10 bags of crisps to have 30 stickers
