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?

Answer:Part (A)  Total Cost = "7 + 5x + 4y + 2z" dollarsPart (B)  $43Step-by-step explanation:Part A)Ticket cost given as $7Then,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" dollarsPart 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 + 2zNow, it is givenx = 4y = 3z = 2So, we have:Total Cost = 7 + 5(4) + 4(3) + 2(2) = 7 + 20 + 12 + 4 = $43
