Respuesta :
If Connor buys 3 snacks at 3 dollars each for himself and his 3 children, the net cost (including movie tickets) would be 88 dollars.
If he buys x amount of snacks, his cost will be determined by C=52+3x or C=52+3*x (both are equivalent, but not everyone knows every way to represent multiplication)
Step-by-step explanation:
To find the cost of the snacks:
Cost = Price*NumberOfSnacks, or C=p*n, or C=pn
To find the unit cost of the snack, find the price, the p value, which is 3 dollars.
Then, find the total number of snacks that will be bought. Since each person receives an equal number of snacks, 3 per person, and there are 4 people (himself and his 3 children), we can multiply 3*4 to find the n value, which is now known to be 12.
C=3*12=36. Add to the 13 dollar per person charge for tickets (52 dollars for 4 people), and you get 88 dollars.
To find the cost if he buys x amount of snacks for himself and his 3 children (assumed to be "everyone"), all costs but the n value are to be the same, creating this equation:
C=52+3x
In this context, 52 is the cost of movie tickets, 3 is the cost of the snacks, and x is the total number of snacks bought. C represents total cost.
The total cost for tickets and 5 snacks is $90.
The total cost for tickets and x snacks is $(65+5x).
Total cost:
Important information:
- Number of kids = 4
- Cost of each ticket = $13
- Cost of each snacks = $5
- Number of snacks = x
The total number of people is 5. So, cost of 5 tickets is:
[tex]5\times 13=65[/tex]
Cost of 5 snacks is:
[tex]5\times 5=25[/tex]
Total cost is:
[tex]65+25=90[/tex]
The total cost for tickets and 5 snacks is $90.
Cost of x snacks is:
[tex]5\times x=5x[/tex]
Total cost is:
[tex]65+5x[/tex]
The total cost for tickets and x snacks is $(65+5x).
