Elian and his friends paid a total of $7 for the tickets to the school football game. while at the game, they bought 5 hot dogs at x dollars each, 4 boxes of popcorn a y dollars each, and 2 pretzels at z dollars each?

part a.) write an expression to show the total cost of admission and the snacks?

part b.) hot dogs cost $4, popcorn cost $3, and pretzel cost $2. what was the total cost for admission and snacks?

Part (A)  Total Cost = "7 + 5x + 4y + 2z" dollars

Part (B)  $43

Step-by-step explanation:

Part A)

Ticket cost given as $7

Then,

5 hotdogs for x dollar each cost

"5x"

Then,

4 box of popcorn at y dollar per box, cost is:

"4y"

Then,

2 pretzels each z dollar, cost is:

"2z"

The total cost is the sum hence,

Total Cost = "7 + 5x + 4y + 2z" dollars

Part B)

Since we now know the cost of hotdogs, popcorn and pretzels, we can find the exact dollar value of total cost.

The expression for total cost was:

7 + 5x + 4y + 2z

Now, it is given

x = 4

y = 3

z = 2

So, we have:

Total Cost = 7 + 5(4) + 4(3) + 2(2) = 7 + 20 + 12 + 4 = $43
